Tsongkhapa ("The man from Tsongkha", 1357–1419), usually taken to mean "the Man from Onion Valley", born in Amdo, was a famous teacher of Tibetan Buddhism whose activities led to the formation of the Gelug school of Tibetan Buddhism. He is also known by his ordained name Losang Drakpa (Wylie: blo bzang grags pa) or simply as "Je Rinpoche" (Wylie: rje rin po che). Also, he is known by Chinese as Zongkapa Lobsang Zhaba, He was the son of a Tibetan Longben Tribal leader who also once served as an official of the Yuan Dynasty of China.
In his two main treatises, the Lamrim Chenmo (Wylie: lam rim chen mo) and Ngakrim Chenmo (Wylie: sngags rim chen mo), Tsongkhapa meticulously sets forth this graduated way and how one establishes oneself in the paths of sutra and tantra.
With a Mongolian father and a Tibetan mother, Tsongkhapa was born into a nomadic family in the walled city of Tsongkha in Amdo, Tibet (present-day Haidong and Xining, Qinghai) in 1357. It is said that the Buddha Sakyamuni spoke of his coming as an emanation of the BodhisattvaManjusri in the short verse from the Root Tantra of Manjushri (Wylie: 'jam dpal rtsa rgyud):
After I pass away
And my pure doctrine is absent,
You will appear as an ordinary being,
Performing the deeds of a Buddha
And establishing the Joyful Land, the great Protector,
According to hagiographic accounts, Tsongkhapa's birth was prophesied by the 12th abbot of the Snar thang monastery, and was recognized as such at a young age, taking the lay vows at the age of three before Rolpe Dorje, 4th Karmapa Lama and was named Künga Nyingpo (Wylie: kun dga' snying po). At the age of seven, he was ordained as a śrāmaṇera by Döndrup Rinchen (Wylie: don grub rin chen, 1309–1385), the first abbott of Jakhyung Monastery (Wylie: bya khyung brag), and was given the ordination name Losang Drakpa (Wylie: blo bzang grags pa).

It was at this early age that he was able to receive the empowerments of Heruka, Hevajra, and Yamantaka, three of the most prominent wrathful deities of Tibetan Buddhism, as well as being able to recite a great many Sutras, not the least of which was Mañjuśrīnāmasamgīti. He would go on to be a great student of the vinaya, the doctrine of behaviour, and even later of the Six Yogas of Naropa, the Kalachakra tantra, and the practice of Mahamudra. At the age of 24, he received full ordination as a monk of the Sakya school.
As an emanation of Manjusri, Tsongkhapa is said have been of "one mind" with Atiśa, received the Kadam lineages and studied the major Sarma tantras under Sakya and Kagyu masters. He also studied with a Nyingma teacher, the siddha Lek gyi Dorjé (Wylie: legs gyi rdo rje) and the abbot of Shalu Monastery, Chö kyi Pel (Wylie: zhwa lus pa chos kyi dpal), and his main Dzogchen master was Drupchen Lekyi Dorje (Wylie: grub chen las kyi rdo je), also known as Namkha Gyaltsen (Wylie: nam mkha' rgyal mtshan, 1326–1401).
In addition to his studies, he engaged in extensive meditation retreats. He is reputed to have performed millions of prostrations, mandala offerings and other forms of purification practice. Tsongkhapa often had visions of iṣṭadevatās, especially of Manjusri, with whom he would communicate directly to clarify difficult points of the scriptures.
Tsongkhapa was one of the foremost authorities of Tibetan Buddhism at the time. He composed a devotional prayer called the Migtsema Prayer to his Sakya master Rendawa, which was offered back to Tsongkhapa, with the note of his master saying that these verses were more applicable to Tsongkhapa than to himself.
Tsongkhapa died in 1419 at the age of sixty-two. After his death several biographies were written by Lamas of different traditions.Wangchuk Dorje, 9th Karmapa Lama, praised Tsongkhapa as one "who swept away wrong views with the correct and perfect ones."Mikyö Dorje, 8th Karmapa Lama, wrote in his poem In Praise of the Incomparable Tsong Khapa:
When the teachings of the Sakya, Kagyue, Kadam
And Nyingma sects in Tibet were declining,
You, O Tsong Khapa, revived Buddha's Doctrine,
Hence I sing this praise to you of Ganden Mountain.
Tsongkhapa was acquainted with all Tibetan Buddhist traditions of his time, and received lineages transmitted in the major schools. His main source of inspiration was the Kadam school, the legacy of Atiśa. Tsongkhapa received two of the three main Kadampa lineages (the Lam-Rim lineage, and the oral guideline lineage) from the Nyingma Lama, Lhodrag Namka-gyeltsen; and the third main Kadampa lineage (the lineage of textual transmission) from the Kagyu teacher Lama Umapa.
Tsongkhapa's teachings drew upon these Kadampa teachings of Atiśa, emphasizing the study of Vinaya, the Tripiṭaka, and the Shastras. Atiśa's Lamrim inspired Tsongkhapa's Lamrim Chenmo, which became a main text among his followers. He also practised and taught extensively the Vajrayana, and especially how to bring the Sutra and Tantra teachings together, wrote works that summarized the root teachings of the Buddhist philosophical schools, as well as commentaries on the Prātimokṣa, Prajnaparamita, Candrakirti's Madhyamakavatara, logic, Pure Land and  the Sarma tantras.
According to Thupten Jinpa, the following elements are essential in a coherent understanding of Tsongkhapa's understanding and interpretation of the Madhyamaka refutation of essentialist ontology:[note 1]
Tsongkhapa's distinction between the domains of the conventional and ultimate perspectives;
Tsongkhapa's insistence on a prior, correct conceptual identification of the object of negation;
Tsongkhapa's differentiation of the various connotations of the all-important term 'ultimate' (paramartha skt.);
Tsongkhapa's distinction he draws between that which is not found and that which is negated.
Tsongkhapa's first principal work, The Golden Garland of Eloquence (Wylie: legs bshad gser phreng) demonstrated a philosophical view in line with the Yogacara school and, as became one of his hallmarks, was more influenced by Indian authors than contemporary Tibetan sources. At this time his account of the Madhyamaka "propounds a philosophy that later Gelukpas [...] call Yogācāra-svātantrika-madhyamaka, [...] yet does not have the authority of Candrakīrti's Prāsaṅgika interpretation."
After this early work, his attention focussed on the Prajnaparamita sutras and Dharmakirti's Pramanavartika, and it is this emphasis that dominates all his later philosophical works. Garfield suggests his stance as:
A complete understanding of Buddhist philosophy requires a synthesis of the epistemology and logic of Dharmakirti with the metaphysics of Nagarjuna
For Tsongkhapa, calming meditation alone is not sufficient, but should be paired to rigorous, exact thinking "to push the mind and precipitate a breakthrough in cognitive fluency and insight."
The opponents of Candrakirti's Prasanna-padā[note 2] are both (a) the essentialists, who accept that things ultimately have intrinsic nature, and (b) the Svātantrikas, who refute that, but accept that things conventionally have intrinsic character or intrinsic nature.
The classification into Prasangika and Svatantrika originated from their different usages of reason to make "emptiness" understandable. The Svātantrikas strive to make positive assertions to attack wrong views, whereas the Prasangikas draw out the contradictory consequences (prasanga) of the opposing views. In Tsongkhapa's reading, the difference becomes one of the understanding of emptiness, which centers on the nature of conventional existence. The Svātantrikas state that conventional phenomena have particular characteristics, by which they can be distinguished, but without an ultimately existing essence. In Tsongkhapa's understanding, these particular characteristics are posited as establishing that conventionally things do have an intrinsic nature, a position which he rejects:
Svatantrikas (like Bhavaviveka) are those Madhyamikas who accept that, at a conventional level, things actually do have intrinsic nature just as they are perceived. To exist at all entails having intrinsic existence. However, since there is nothing that holds up under ultimate analysis, everything is ultimately empty. Emptiness is the lack of ultimate existence.
Although Tsongkhapa is regarded as the great champion of the Prasangika-view, according to Thomas Doctor, Tsongkhapa's views on the difference between Prasanghika and Svatantrika are preceded by a 12th-century author, Mabja Jangchub Tsondru (d. 1185).
Tsongkhapa nevertheless argues that the Prāsaṅgika's use of reductio ad absurdum is also syllogistic, because one "refutes the opponent using a subject, a reason, and so forth that are accepted by that opponent."[note 3]
Conventional valid cognition
While objecting to Bhavaviveka's understanding of a shared object at the conventional level, Tsongkhapa has to leave intact conventional reality and causality, to keep intact the teachings on cyclic existence and the basis for moral behavior. Therefore, he has to explain how conventional reality is perceived in a valid way, which he does by introducing "conventional valid cognition."
According to Tsongkhapa, following Candrakirti, all phenomena are empty of inherent existence or essence, because they are dependently co-arisen with (created by) mental imputation.[note 4] All phenomena in all possible worlds lack inherent existence and come into existence relative to a designating consciousness which co-arises with that phenomenon.[note 5]
From the Prāsaṅgika perspective, in order for something to exist, it must be designated validly by a designating consciousness. To talk about an object that does not exist in relation to a subject is incoherent.[note 6][note 7] Anything which comes into existence through valid designation is part of "conventional reality" or "conventional truth." According to Lama Tsongkhapa, something is validly designated (exists conventionally) if it meets all of the following three conditions:
It is known to a conventional consciousness;
No other conventional cognition (within that convention) contradicts it from being thus known;
Reason that accurately analyzes reality — that is, analyzes whether something intrinsically exists — does not contradict it.
Whatever fails to meet those criteria does not exist, and relationships between objects cannot exist without being validly designated into existence.[note 8][note 10]
Nevertheless, Prāsaṅgika are not stating that nothing exists, but instead, hold that phenomena only come into existence co-dependently with minds which are applying conceptual and nominal conventions to uncharacterized mere experiences. Things and phenomena do exist co-dependently, based upon a relationship with a knowing and designating mind, but nothing exists - including the fundamental characteristics which compose our experience - in an independent, self-arising, or self-sustaining manner.
Identifying the correct Object of Negation
For Tsongkhapa, extended rational analysis is required to correctly establish what it is that is to be negated.[note 12] This correct establishment is necessary to reach a liberating insight into emptiness, while avoiding the trap of nihilism, the possibility that "seeming reality becomes extinct or invalidated if a phenomenon is empty of that very phenomenon."
While the "I" or self is accepted as nominally existing in a conventional way,[note 13] for Tsongkhapa, following Candrakirti, the object to be negated by reason is the "metaphysical fiction" of an intrinsic nature which is "erroneously reified." Tsongkhapa argues that "there exists within each of us a natural belief, [a naive, normal, pre-philosophical way of seeing the world], which leads us to perceive things and events as possessing some kind of intrinsic existence and identity." It is this mistaken perception which is the object to be negated.[note 14][note 15]
According to Tsongkhapa, Buddhist (in concreto, the Sarvastivada) and non-Buddhist essentialist schools are not negating the correct object, but are only negating "imaginary constructs" and "acquired ignorance," not the innate perception of an inherently existing self.[note 16] They have "realized only a coarse selflessness and having thereby suppressed, but not removed from the root, the obstructions to liberation."[note 17] According to Tsongkhapa, the negation of acquired, philosophical notions won't eradicate the afflictions or free one from cycles of rebirth.[note 18] The negation has to go further, since the object of negation is not an acquired, philosophical notion of a permanent self, but the innate perception of an inherently existing self.[note 19]
Gyumed Khensur Rinpoche Lobsang Jampa, referring to Kalden Gyatso, notes that "there are actually two objects that must be refuted or destroyed," namely this sense of "I," and the subjective self, "the mind grasping at that false 'I'." By analyzing the sense of "I" and its logical contradictions, its seemingly true existence is seen through, which "destroys the continuum of the subjective mind grasping it. What continues is a wisdom mind."
Lack of Intrinsic Nature
According to Patrick Jennings,
Tsongkhapa describes a procedure for establishing the non-existence of a substantial, abiding essence in either the self or in 'exterior' phenomena, such as pots or potatoes. It is essential during this procedure that one does not confuse the non-findability of a substantial, non-relational self with the refutation of the existence of a relative or conventional self – the self as it appears to ordinary cognition and which is subject to the law of cause and effect.
This procedure is described in chapter 23, The person Lacks Intrinsic Nature, of volume three of the Lamrim Chenmo, and entails four steps:
The refutation of the position that the self is one with the aggregates
The refutation of the position that the self is different from the aggregates
How those arguments also refute each of the remaining positions
How the person appears like an illusion based on that refutation
Tsongkhapa saw emptiness as a consequence of pratītyasamutpāda (dependent arising), the teaching that no dharma ("thing") has an existence of its own, but always comes into existence in dependence on other dharmas. According to Tsonghkhapa, dependent-arising and emptiness are inseparable.[note 20][note 21]
Tsongkhapa's view on "ultimate reality" is condensed in the short text In Praise of Dependent Arising, also known as In Praise of Relativity and The Essence of Eloquency. It states that "things" do exist conventionally, but ultimately everything is dependently arisen, and therefore void of inherent existence:
Whatever depends on causes and conditions Is empty of intrinsic reality What excellent instruction could there be More marvellous than this discovery?
This means that conventionally things do exist, and that there is no use in denying that. But it also means that ultimately those things have no 'existence of their own', and that cognizing them as such results from cognitive operations, not from some unchangeable essence. Tsongkhapa:
Since objects do not exist through their own nature, they are established as existing through the force of convention.
According to Tsongkhapa, emptiness is empty of inherent existence: emptiness only exists nominally and conventionally. Emptiness is co-dependently arisen as a quality of conventional phenomena and is itself a conventional phenomenon. There is no "transcendental ground," and "ultimate reality" has no existence of its own, but is the negation of such a transcendental reality, and the impossibility of any statement on such an ultimately existing transcendental reality: it is no more than a fabrication of the mind. Emptiness is an ultimate truth (a fact which applies to all possible phenomena, in all possible worlds), but it is not an ultimate phenomenon or ultimate reality (something which has always existed, is self-created, and is self-sustaining). It is also not a "Tao" or a primal substance from which all other things arise. Buddhapalita:
There is no way to overcome the misconceptions of those who think that emptiness is a real thing. For example, if you tell someone, 'I have nothing.' and that person says, 'Give me that nothing.' How could you make that person understand that you have nothing?
Susan Kahn further explains:
Ultimate truth does not point to a transcendent reality, but to the transcendence of deception. It is critical to emphasize that the ultimate truth of emptiness is a negational truth. In looking for inherently existent phenomena it is revealed that it cannot be found. This absence is not findable because it is not an entity, just as a room without an elephant in it does not contain an elephantless substance. Even conventionally, elephantlessness does not exist. Ultimate truth or emptiness does not point to an essence or nature, however subtle, that everything is made of.
A prominent and important feature of the Prāsaṅgika approach is their use of the non-affirming negation.[note 22] A non-affirming negation is a negation which does not leave something in the place of what has been negated. For instance, when one says that a Buddhist should not drink alcohol, they are not affirming that a Buddhist should, in fact, drink something else. One is merely negating the consumption of alcohol under a particular circumstance.[note 23][note 24]
According to Tsongkhapa, for the Prāsaṅgika the philosophical position of emptiness is itself a non-affirming negation, since emptiness is a "lack of inherent existence." One is not affirming anything in the place of that absence of inherence. It is not the presence of some other quality. If one were to describe emptiness as the presence of some quality -for example, a "voidness" or a "thusness" - it would linguistically and philosophically contradict the nature of the object which it is attempting to characterize.
Rejection of the storehouse-consciousness
The dawning realization of emptiness can be frightening, arousing "fear of annihilation." Some Mahayana sutras therefore argue that the so-called storehouse consciousness or mind-basis-of-all consciousness was taught by the Buddha "provisionally, for the benefit of those who could be helped by believing in its existence but who would be harmed by hearing the teachings about emptiness."
Tsongkhapa adheres to this provisional adherence of the storehouse-consciousness, but rejects it as faulty once one has gained insight into emptiness. He presents the alternative viewpoint of "the mere 'I'" which carries karma from life-to-life and uses other techniques to overcome the fear of annihilation.[note 25]
Sam van Schaik says that Tsongkhapa "wanted to create something new" and that the early Gandenpas defined themselves by responding to accusations from the established schools:
Though the Sakya had their own teachings on these subjects, Tsongkhapa was coming to realize that he wanted to create something new, not necessarily a school, but at least a new formulation of the Buddhist Path.
Monasticism and lineage
Tsongkhapa emphasised a strong monastic Sangha. With the founding of the Ganden monastery in 1409, he laid down the basis for what was later named the Gelug ("virtuous ones") order. At the time of the foundation of the Ganden monastery, his followers became to be known as "Gandenbas." Tsongkhapa himself never announced the establishment of a new monastic order.
After Tsongkhapa had founded Ganden Monastery in 1409, it became his main seat. He had many students, among whom Gyaltsab Je (1364–1431), Khedrup Gelek Pelzang, 1st Panchen Lama (1385–1438), Togden Jampal Gyatso, Jamyang Choje, Jamchenpa Sherap Senge, and the 1st Dalai Lama (1391–1474), were the most outstanding. After Tsongkhapa's passing his teachings were held and kept by Gyaltsab Dharma Rinchen and Khedrub Gelek Pälsang. From then on, his lineage has been held by the Ganden Tripas, the throne-holders of Ganden Monastery, among whom the present one is Thubten Nyima Lungtok Tenzin Norbu, the 102nd Ganden Tripa.
After the founding of Ganden Monastery by Tsongkhapa, Drepung Monastery was founded by Jamyang Choje, Sera Monastery was founded by Chöje Shakya Yeshe and the 1st Dalai Lama founded Tashilhunpo Monastery. Many Gelug monasteries were built throughout Tibet but also in China and Mongolia. He spent some time as a hermit in Pabonka Hermitage, which was built during Songsten Gampo times, approximately 8 kilometres north west of Lhasa. Today, it is also part of Sera.
Among the many lineage holders of the Gelugpas there are the successive incarnations of the Panchen Lama as well as the Chagkya Dorje Chang, Ngachen Könchok Gyaltsen, Kyishö Tulku Tenzin Thrinly, Jamyang Shepa, Phurchok Jampa Rinpoche, Jamyang Dewe Dorje, Takphu Rinpoche, Khachen Yeshe Gyaltsen, Trijang Rinpoche, Domo Geshe Rinpoche, and many others.
The annual Tibetan prayer festival Monlam Prayer Festival was established by Tsongkhapa. There he offered service to ten thousand monks. The establishment of the Great Prayer Festival is seen as one of his Four Great Deeds. It celebrates the miraculous deeds of Gautama Buddha.
Western understanding of Madhyamaka
According to Karl Brunnholzl, Tsongkhapa's Madhyamaka has become widely influential in the western understanding of Madhyamaka:
First, with a few exceptions, the majority of books or articles on Madhyamaka by Western - particularly North American - scholars is based on the explanations of the Gelugpa school of Tibetan Buddhism. Deliberately or not, many of these Western presentations give the impression that the Gelugpa system is more or less equivalent to Tibetan Buddhism as such and that this school's way of presenting Madhyamaka is the standard or even the only way to explain this system, which has led to the still widely prevailing assumption that this is actually the case. From the perspective of Indian and Tibetan Buddhism in general, nothing could be more wrong. In fact, the peculiar Gelugpa version of Madhaymaka is a minority position in Indo-Tibetan Buddhism, since its uncommon features are neither found in any Indian text nor accepted by any of the other Tibetan schools.
Some of the greatest subsequent Tibetan scholars have become famous for their own works either defending or attacking Tsongkhapa's views.[note 26]
Tsongkhapa's rejection of Svatantrika has been criticised within the Tibetan tradition, qualifying it as Tsongkhapa's own invention, "novelties that are not found in any Indian sources," and therefore "a major flaw" and "unwarranted and unprecedented within the greater Madhyamaka tradition."[note 27]
According to Thupten Jinpa, the Gelugpa school sees Tsongkhapa's ideas as mystical revelations from the bodhisattva Manjusri,[note 28] whereas Gorampa accused him of being inspired by a demon.[note 29] Brunnhölzl further notes that, according to his Karma Kagyü (Mahamudra) critics, Tsongkhapa was mistaken in some regards in his understanding of emptiness, taking it as a real existent, and thereby hindering the liberation of his followers.[note 30] According to Van Schaik, these criticisms furthered the establishment of the Gelupga as an independent school:
As Khedrup and later followers of Tsongkhapa hit back at accusations like these, they defined their own philosophical tradition, and this went a long way to drawing a line in the sand between the Gandenpas and the broader Sakya tradition.
Hornlike object of negation
Karl Brunnholzl notes that Tsongkhapa's "object of negation," the "phantom notion of 'real existence' different from the 'table that is established through valid cognition'," is called a "hornlike object of negation" by his critics: Tsongkhapa first puts a horn on the head of the rabbit, and then removes it again, a maneuver which "affects neither the rabbit's existence nor your taking the rabbit for a rabbit." According to Brunnholzl,
This is precisely why it is said that such an approach to the object of negation is not suitable for relinquishing the reifying clinging to persons and phenomena and thus does not lead to liberation from cyclic existence. Through negating the hornlike object of negation called “real existence” with regard to a table, we will neither relinquish the clinging to the reality of this table nor realize its ultimate nature.[note 31]
Tsongkhapa promoted the study of logic, encouraged formal debates as part of Dharma studies, and instructed disciples in the Guhyasamāja, Kalacakra, and Hevajra Tantras. Tsongkhapa's writings comprise eighteen volumes, with the largest amount being on Guhyasamāja tantra. These 18 volumes contain hundreds of titles relating to all aspects of Buddhist teachings and clarify some of the most difficult topics of Sutrayana and Vajrayana teachings. Tsongkhapa's main treatises and commentaries on Madhyamaka are based on the tradition descended from Nagarjuna as elucidated by Buddhapālita and Candrakīrti.
Major works among them are:

^According to Thupten Jinpa, Tsongkhapa's interpretation of the Madhyamaka's key tenets is to be regarded as an important lineage within the Buddhist religious and philosophical milieu, sharing the basic soteriological concerns of the Buddhist path.
^A seminal text regarding the Prāsaṅgika/Svātantrika distinction
^For example, if cause-effect relationships occur because the sprout itself produces the effect of being a sprout (self-arising), then this "would mean that something that already exists is being produced, [and] production would be purposeless and endless [... if] contradictions are assembled in this way, the only result is that the opponents understand them and abandon" wrong tenets. To clarify with a more modern rendition: if 500 people were shown 100,000 slides of a seed turning into a small plant, would we expect them all to agree that on slide number 1,008 the seed causes the sprout? If one argues that the seed objectively and independently causes the sprout (other-arising) or that the sprout causes itself (self-arising) at the material level, then everyone would be forced to agree that this event occurs at a particular time. However, because the sprout arises relative to a conscious observer who designates the term-concept "sprout" onto the continuum of slides, we find that almost no one can agree where the seed ceases and the sprout arises. This is because the cause-effect relationship cannot be found at the objective material level. The cause-effect relationship is also dependently designated, a viewpoint which is established by Lama Tsongkhapa, Nagarjuna, and Buddapalita.
^According to Jay Garfield, "[a] fundamental tenet of any Buddhist school is that all phenomena are dependently originated. In Madhyamaka Buddhist thought, following Candrakrti [...], this dependency is glossed in three ways":
Pratītyasamutpāda or 'dependent arising.' All things arise in dependence on causes and conditions, and cease when those causes and conditions are no longer present.[subnote 1]
All wholes are dependent upon their parts for existence, and all parts are dependent on their wholes for existence.[subnote 2]
^"Thus, [Chandrakirti] says that those are synonyms. 'Without depending on another' does not mean not depending on causes and conditions. Instead, 'other' refers to a subject, i.e., a conventional consciousness, and something is said not to depend on another due to not being posited through the force of that conventional consciousness."
^A parallel in western thought can be found in the viewpoint of intentionality: "
Every mental phenomenon is characterized by what the Scholastics of the Middle Ages called the intentional (or mental) inexistence of an object, and what we might call, though not wholly unambiguously, reference to a content, direction towards an object (which is not to be understood here as meaning a thing), or immanent objectivity. Every mental phenomenon includes something as object within itself, although they do not all do so in the same way. In presentation something is presented, in judgment, something is affirmed or denied, in love loved, in hate hated, in desire desired and so on. This intentional in-existence is characteristic exclusively of mental phenomena. No physical phenomenon exhibits anything like it. We could, therefore, define mental phenomena by saying that they are those phenomena which contain an object intentionally within themselves.

^In Ocean of Reasoning, Tsongkhapa and Nagarjuna spell out various analysis to the effect that phenomena cannot possibly exist without mental imputation. The list includes: "causes" including Conditions, Motion, the Senses, the Aggregates, the Elements, Desire & the Desirous One, "Arising, Enduring, & Ceasing," Agent & Action, Prior Entity, Fire & Fuel, Beginning & End, Suffering, Compounded Phenomena, Contact, Essence, Bondage, Action, Self & Phenomena, Time, Assemblage, Becoming & Destruction, the Buddha, Errors, the Four Noble Truths, Nirvana, the Twelve Links of Dependent Origination, and Views. 
^In Kelsang Gyatso's Lorig translation: "The definition of mind is that which is clarity and cognizes. This definition, 'clarity' refers to the nature of mind, and 'cognizes to the function of mind."
According to Lama Tsongkhapa's interpretation of Nagarjuna, both causes and effects are also merely designated by mind. It is mind that determines that a cause has ceased and its effect is now in existence.[subnote 7] It is also mind which determines that some collection of parts is now considered to be a whole.[subnote 8] Even mind itself is empty of inherently existing in the Prasangika.[subnote 9] The relationship between object and subject is also empty of inherent existence. In Prasangika, all things of samsara and nirvana are merely designated.[subnote 10]
^It is unclear which specific school of thought Tsongkhapa refers here to.
^In his Lamrim Chenmo, Tsongkhapa refers to opponents[note 11] who argue that it is absurd "to conduct the extensive rational analysis required for refutations and proofs [which] is to meander among mere conventional words," because "if something exists, it cannot be refuted, and, if it does not exist, it need not be refuted."  In response, Tsonghkhapa refers to Nagarjuna’s Refutation of Objections, among other texts, : "What use is it to establish the negation if what does not exist anyway, even without words? To answer that, the words “does not exist” Cause understanding; they do not eliminate."
HTsongkhapa also quotes Nagarjuna's Commentary on Refutation of Objections: "The words, “All things lack intrinsic nature,” do not cause things to lack intrinsic nature, but, in the absence of intrinsic nature, they do make it understood that things lack intrinsic nature."
Tsongkhapa then gives the following paraphrased example. If a person named Devadatta is not in the house, but someone says, “Devadatta is in the house.” Then in order to show that Devadatta is not there, someone else will say, “Devadatta is not there.” Those words do not cause Devadatta not to be there but allow the first person to understand that Devadatta is not in the house. Similarly, the words, “Things lack intrinsic nature,” do not cause things to lack intrinsic nature, but help the those confused by ignorance to gain a valid cognition of reality.
^See: * Hopkins: "[I]f you have understood the view of the Middle Way School, you may conceive the I as only being nominally existent." * Tsongkhapa: "“self” refers to mere essential or intrinsic existence and also refers to the object of an awareness that simply thinks, “I.” Of these two, the former is the object negated by reason, whereas the latter is accepted conventionally, so it is not refuted."
^It is the conception that conventional phenomena have an "ontological status—a way of existing—in and of themselves, without being posited through the force of an awareness."Tsongkhapa goes on to say: "The referent object that is thus apprehended by that ignorant conception, the independent ontological status of those phenomena, is identified as [the] hypothetical “self” or “intrinsic nature.” Lama Tsongkhapa further explains: "Suppose that we leave aside analysis of how [phenomena] appear—i.e., how they appear to a conventional awareness—and analyze the objects themselves, asking, 'What is the manner of being of these phenomena?' We find they are not established in any way. Ignorance does not apprehend phenomena in this way; it apprehends each phenomenon as having a manner of being such that it can be understood in and of itself, without being posited through the force of a conventional consciousness. According to Tsongkhapa, "[that] what exists objectively in terms of its own essence without being posited through the power of a subjective mind is called [...] 'intrinsic nature'” or ignorance Tsongkhapa goes on to say: "The absence of this quality in the person is called the selflessness of the person; its absence in phenomena such as eyes, ears, and so forth is called the selflessness of objects. Hence, one may implicitly understand that the conceptions of that intrinsic nature as present in persons and objects are the conceptions of the two selves."
^The Indo-Tibetan rope & snake analogy explains this further. Under low light, the thought might arise that a striped rope on the ground is a snake, "but there is nothing on top of or inside this rope [...] to which we could" validly apply the term and therefore establish a conventionally existing snake.
The Dalai Lama expands: "Like this example, a thought of 'me' may arise on the basis of the aggregate factors of our experience. But there is nothing about these aggregates as the basis for labeling - not any of their parts, nor the collection or network of their parts, nor their continuum over time, nor something separate and apart from them - which is a basis with the defining characteristic making it 'me,' to which we could possibly apply the name 'me.' That being the case, this 'me' is nothing more than simply what can be designated by a mental label on the basis of aggregate factors of experience.
In reality, the self of persons, objects, and abstracts is like the term-concept "snake" being designated upon a rope, "the snake is merely what can be designated by a mental label." Like this, the object of negation or ignorance is viewed to be the thought and perception which grasps the self of persons and objects to be established within their respective bases of designation. To put this in somewhat simpler terms, the thought and perception which grasps persons, things, and abstracts phenomena as existing in-and-of themselves - with characteristics or an identity of their own - is seen to be ignorance in this system.
^Tsonghkhapa: "Based on just this [intrinsic nature], the referent object of the way that ignorance apprehends things as explained above, essentialist schools—Buddhist and non-Buddhist—reify many different things. When you negate the referent of ignorance’s cognitive process, you completely stop all of these tenet-driven reifications, as though you cut a tree at its root. Therefore, those who have the faculty of wisdom should understand that the referent object of innate ignorance is the basic object of negation and should not devote themselves merely to refuting imaginary constructs that are imputed only by the advocates of philosophical tenets. [...] What binds all living beings in cyclic existence is innate ignorance; acquired ignorance exists only among those who advocate philosophical tenets, so it cannot be the root of cyclic existence. It is extremely important to gain specific and certain knowledge of this point."
^Daniel Cozart explaining this idea in greater detail:"A second category of tenets is concerned with implications of the Mahayana and Hinayana path structures. For the most part, they are tenets propounded to demonstrate that some persons who are regarded by other schools as Arhats liberated beings-are only ersatz Arhats, having realized only a coarse selflessness and having thereby suppressed, but not removed from the root, the obstructions to liberation. These tenets, then, revolve around the unique Prasangika assertion that the root of cyclic existence is the conception of inherent existence, which is more subtle than the conception of a self described by other systems of tenets. Five assertions are elucidated in this regard:
One must realize emptiness in order to become liberated and therefore some "Arhats" who have only realized a coarse selflessness are not actually liberated.
There is desire that either is, or is thoroughly mixed with, the conception of true existence, and so-called Arhats still have this sort of desire.
Although some of these "Arhats" do indeed have yogic direct perception of the four noble truths, one does not have to be an Arhat or even a Superior (one who has directly realized emptiness) in order to have such yogic direct perception.
Although some of these "Arhats" have indeed realized the coarse aspects of the four noble truths, such a realization is not sufficient to overcome the obstructions to liberation.
Since true cessations, the irrevocable cessation of some portion of the afflictions of desire, hatred, etc., are also emptinesses, such "Arhats" who have not realized emptiness could not have experienced true cessations, i.e., could not have overcome the afflictive obstructions."
^Tsongkhapa: "If you do not understand this and fail to eradicate the perspective of innate ignorance, then, when you refute a personal self, you will only refute a self that is permanent, unitary, and independent [...] Even if you actualized such a selflessness in meditation and consummated your cultivation of it, nothing would come of it. It would be extremely absurd to claim that you can overcome innate afflictions by seeing as nonexistent the two selves imputed by acquired misconceptions."
^Chandrakirti: "When knowing selflessness, some eliminate a permanent self, but we do not consider this to be the basis of the conception of "I." It is therefore astonishing to claim that knowing this selflessness expunges and uproots the view of the self. [This is equivalent to] if someone sees a snake living in the wall of his house. To ease his concern, someone else says, 'there is no elephant there.' Alas, to others it is ridiculous that this would expel the fear of the snake.
^They exist in a relationship of entity or identity. A relationship of entity or identity is one in which two objects are merely conceptually distinct, but not actually distinct. For example, the relationship between the mental categorization of a dog and that of an animal, with regards to the same being. If it is a dog, then it must also be an animal. Additionally, this relationship applies to impermanent phenomena and products: if it's impermanent, it must be a product.
"Form is empty. Emptiness is form.
Emptiness is not other than form; form is also not other than emptiness.
In the same way, feeling, discrimination, compositional factors, and consciousness are empty.
Shariputra, likewise, all phenomena are emptitness; without characteristic;
unproduced, unceased; stainless, not without stain; not deficient, not fulfilled."
^Pabongka Rinpoche states in Liberation in Our Hands that if we can not correctly "recognize the nature of the false mode of existence that is being denied, we will not be able to realize the simple negation [Skr. prasajyapratisedhah or non-affirming negation] that is established through its refutation."
^"[A non-affirming negation is defined as] a negative object in which no further entity is implied when the mind negates the object that is related to it."
^Another example can be found in the debate over the use of the terms "devoid of nature itself" in Gelug Mahamudra (non-affirming negation) and "that which has voidness as its nature" in non-Gelug Mahamudra and Dzogchen (an affirming negation).
^According to the Gelugpa, the Chittamatra hold that the mind-basis-of-all consciousness is that which bears the karmic seeds and is findable upon analysis. That is, "if one sought the basis of the designation of the person one would discover the mind-basis-of-all." The Madhyamika-Prasangika posit that beings accumulate karma and experience their effects without the mind-basis-of-all? They posit that karma is carried on the mere "I" which is dependently designated on the basis of the aggregates, stating that "it is a sufficient basis with which to associate the factors of disintegratedness (karma)." Daniel Cozant expands by saying that since phenomena are neither inherently created nor inherently destroyed according to Prasangika, that "therefore, the possibility of a later effect is not precluded."
^According to Brunnhölzl, writing from a Karma Kagyü (Mahamudra) point of view on Madhyamaka, "All critics of Tsongkhapa, including the Eighth Karmapa, agree that many features of his Centrism are novelties that are not found in any Indian sources and see this as a major flaw." Yet, Brunnhölzl also notes that "the point here is whether what is said accords with and serves to accomplish the Buddha’s fundamental concern of liberation from cyclic existence and attaining Buddhood."
^Thupten: "The traditional Geluk understanding of these deviations in Tsongkhapa's thought attributes the development of his distinct reading of Madhyamaka philosophy to a mystical communion he is reported to have had with the bodhisattva Manjusri [...] It is interesting that the tradition Tsongkhapa is claiming to honour is, in a strict sense, not the existing system in Tibet; rather, it appears to be in the tradition of Manjusri as revealed in a mystic vision!
^Sonam Thakchoe or José Cabezón: "Gorampa, in the Lta ba ngan sel (Eliminating the Erroneous View), accuses Tsongkhapa of being "seized by demons" (bdud kyis zin pa) and in the Lta ba'i shan 'byed (Distinguishing Views) decries him as a "nihilistic Madhyamika" (dbu ma chad lta ba) who is spreading "demonic words" (bdud kyi tshig)."
^According to Karmapa Mikyö Dorje, as described by Brunnhölzl, there are "two main types of misunderstanding emptiness: 1) misconceiving emptiness as utter nonexistence 2) misconceiving emptiness as a real entity" Emptiness can be misconstrued as a real entity in two ways: "Tsongkhapa and his followers claim that emptiness is an existent and thus the actual nature of entities, which are its supports. Most other Tibetans in this category, such as Dölpopa and Sakya Chogden, say that only emptiness (which is really established) exists, whereas, ultimately, all other phenomena of the seeming level do not exist. Both of these views are mistaken with regard to the path to liberation.
^The subtle difference between "conventional existence" and "true existence," and the dangers it entails when not understanding it, has also been noted and accepted by later critics of Tsongkhapa, such as Mipham Rinpoche. Padmakara Translation Group: "Mipham Rinpoche attacked it tirelessly as a pernicious distortion that actively hinders the experience of the absence of conceptual construction, which alone is the hallmark of the true realization of emptiness. It is clear, however, that Mipham’s attack was not directed at Tsongkhapa personally, about whom he invariably speaks in respectful terms. His critique, like that of Gendun Chöpel in his Ornament of Nagarjuna’s Meaning, is directed at a possible misrepresentation of Tsongkhapa’s meaning, resulting in what Jeffrey Hopkins refers to as a "pedagogical fault." The assertion that 'the pot is not empty of pot but of true existence' — by someone for whom the distinction between the object of negation and the basis of negation means nothing on the experiential or even intellectual level — far from calling into question the apparent reality of phenomena, tends instead to confirm the deep-rooted habitual belief in substantial reality. In the last analysis, it is a species of realism. It involves a separation of the two truths and is in practice indistinguishable from Bhavaviveka’s Svatantrika assertion that phenomena, though empty ultimately, exist according to their characteristics on the conventional level."
^"All things arise in dependence on causes and conditions, and this is the meaning of dependent origination".
^"Although both from the standpoint of reality and from that of everyday life, The sevenfold reasoning shows that a chariot cannot be established, in everyday life, without analysis it is designated in dependence on its parts."
^"Although dependent origination is generally maintained to be dependence upon conditions, from our perspective, this is not inconsistent with [them existing in] dependence upon mundane nominal conventions."
^The 14th Dalai Lama: "When the issue of how do ultimately unfindable things actually exist becomes unbearable and we have to say something, the bottom line is that their existence is established by virtue simply of names. In other words, the existence of these things is established and proven by virtue simply of the fact that they can be named within the context of mental labeling. There is no additional need for an inherent, findable, defining characteristic on the side of the basis for labeling rendering things existent and giving them their identity. Thus the existence of ultimately unfindable things is merely conventional."
^Tsongkhapa quoting Nagarjuna: "All things are emtpy by nature. Therefore, the unexcelled Tathagata taught the dependent origination of phenomena. That is the supreme meaning. The Buddha, relying on worldly conventions, states that all the various phenomena are in reality designated." Tsongkhapa goes on to say: "The ultimate mode of the existence of things is nothing but their absence of essence - that is, their being dependently originated. Hence, it is explained that all such things as arising are established as imputed through the power of convention [...] [T]he meaning of 'conventional existence' [had it not been spelled out in this way] would not be understood to be established as existent merely through the force of nominal convention." (emphasis original)
^To exemplify this, Lama Tsongkhapa quotes Buddhapalita's response to an Abhidharmica's objection: "It is utterly impossible for time, [causes, effects, and collections of causes and conditions] and such to exist essentially, as you imagine. However, they are established as dependent designation."
According to Lama Tsongkhapa, referring to Buddhapalita, this was one of the points of Nagarjuna's Chatuṣkoṭi. Tsongkhapa: "Buddhapalita says, "Nor do things arise from others, because then anything could arise from anything." [Tsongkhapa continues] Here, the reason why the absurd consequence of "if there was arising from another, anything could arise from anything" is presented is that the "other" in "arising from other" is not just something that is different in virtue of being the referent of a different noun, but something that is inherently existent as different. If it existed in that way, then the sprout's depending on the seed would be inconsistent; thus, their relation would be refuted. If [the sprout] were to arise from another unrelated object, then it would arise from anything!
^Chandrakirti, in the Seven-Point Analysis of a Chariot: "A chariot is neither asserted to be other than its parts, nor to be non-other. It does not possess them. It does not depend on the parts and the parts do not depend on it. It is neither the mere collection of the parts, nor is it their shape. It is like this." ... a chariot is a mere imputation since it does not exist in these seven ways."
^In The Gelug/Kagyu Tradition of Mahamudra, the Dalai Lama states that if we scrutinize "the abiding, deepest nature of mind itself as mere clarity and awareness,[note 9] we see that its existence is established by virtue simply of the fact that is can be mentally labeled." This mental label "mind" is applied to "a continuity of former and later moments of cognition."
^From the 1st Panchen Lama's Lozang Chokyi Gyeltsen, one of Tsongkhapa's five main disciples, The Main Road of the Triumphant Ones: "Before the face of proper, total absorption on the actual nature of reality, there is just the severance of fantasized, impossible extremes - namely, inherent, findable existence or total non-existence - with respect to everything of samsara and nirvana. Yet, after you arise, when you inspect, you see that your mind still gives rise to the appearance of things that dependently arise, which do function and can only exist as simply what can be labeled by names. It is unmistakable that such things still naturally dawn, yet they are like dreams, mirages, reflections of the moon in water, and illusions."
