Karma (Sanskrit, also karman, Pāli: kamma) is a Sanskrit term that literally means "action" or "doing". In the Buddhist tradition, karma refers to action driven by intention (cetanā) which leads to future consequences. Those intentions are considered to be the determining factor in the kind of rebirth in samsara, the cycle of rebirth.
Karma (Sanskrit, also karman, Pāli: kamma, Tib. las) is a Sanskrit term that literally means "action" or "doing". The word karma derives from the verbal root kṛ, which means "do, make, perform, accomplish."
One sows a seed, there is a time lag during which some mysterious invisible process takes place, and then the plant pops up and can be harvested.
Buddhist understanding of karma
Tibetan Bhavacakra or "Wheel of Life" in Sera, Lhasa.
Karma and karmaphala are fundamental concepts in Buddhism. The concepts of karma and karmaphala explain how our intentional actions keep us tied to rebirth in samsara, whereas the Buddhist path, as exemplified in the Noble Eightfold Path, shows us the way out of samsara.
Rebirth,[note 2], is a common belief in all Buddhist traditions. It says that birth and death in the six realms occur in successive cycles driven by ignorance (avidyā), desire (trsnā), and hatred (dvesa). The cycle of rebirth is called samsāra. It is a beginningless and ever-ongoing process. Liberation from samsāra can be attained by following the Buddhist Path. This path leads to vidyā, and the stilling of trsnā and dvesa. Hereby the ongoing process of rebirth is stopped.
Intention (cetana) I tell you, is kamma. Intending, one does kamma by way of body, speech, & intellect.[web 1][note 4]
According to Peter Harvey,
It is the psychological impulse behind an action that is 'karma', that which sets going a chain of causes culminating in karmic fruit. Actions, then, must be intentional if they are to generate karmic fruits.
And according to Gombrich,
The Buddha defined karma as intention; whether the intention manifested itself in physical, vocal or mental form, it was the intention alone which had a moral character: good, bad or neutral [...] The focus of interest shifted from physical action, involving people and objects in the real world, to psychological process.
According to Gombrich, this was a great innovation, which overturns brahmanical, caste-bound ethics. It is a rejection of caste-bound differences, giving the same possibility to reach liberation to all people, not just Brahmanins:
Not by birth is one a brahmin or an outcaste, but by deeds (kamma).[note 5]
How this emphasis on intention was to be interpreted became a matter of debate in and between the various Buddhist schools.[note 6]
Karma leads to future consequences, karma-phala, "fruit of action". Any given action may cause all sorts of results, but the karmic results are only those results which are a consequence of both the moral quality of the action, and of the intention behind the action.[note 7] According to Reichenbach,
[T]he consequences envisioned by the law of karma encompass more (as well as less) than the observed natural or physical results which follow upon the performance of an action.
The "law of karma" applies
...specifically to the moral sphere[.] [It is] not concerned with the general relation between actions and their consequences, but rather with the moral quality of actions and their consequences, such as the pain and pleasure and good or bad experiences for the doer of the act.
Good moral actions lead to wholesome rebirths, and bad moral actions lead to unwholesome rebirths.[quote 3][quote 4] The main factor is how they contribute to the well-being of others in a positive or negative sense. Especially dāna, giving to the Buddhist order, became an increasingly important source of positive karma.
How these intentional actions lead to rebirth, and how the idea of rebirth is to be reconciled with the doctrines of impermanence and no-self,[quote 5] is a matter of philosophical inquiry in the Buddhist traditions, for which several solutions have been proposed. In early Buddhism no explicit theory of rebirth and karma is worked out, and "the karma doctrine may have been incidental to early Buddhist soteriology." In early Buddhism, rebirth is ascribed to craving or ignorance.
The Buddha's teaching of karma is not strictly deterministic, but incorporated circumstantial factors, unlike that of the Jains.[quote 7] It is not a rigid and mechanical process, but a flexible, fluid and dynamic process, and not all present conditions can be ascribed to karma.[note 11][quote 8] There is no set linear relationship between a particular action and its results. The karmic effect of a deed is not determined solely by the deed itself, but also by the nature of the person who commits the deed, and by the circumstances in which it is committed.
Karma is also not the same as "fate" or "predestination".[web 6]
Karmic results are not a "judgement" imposed by a God or other all-powerful being, but rather the results of a natural process.[quote 9] Certain experiences in life are the results of previous actions, but our responses to those experiences are not predetermined, although they bear their own fruit in the future.[quote 10] Unjust behaviour may lead to unfavorable circumstances which make it easier to commit more unjust behavior, but nevertheless the freedom not to commit unjust behavior remains.
The real importance of the doctrine of karma and its fruits lies in the recognition of the urgency to put a stop to the whole process. The Acintita Sutta warns that "the results of kamma" is one of the four incomprehensible subjects,[web 7] subjects that are beyond all conceptualization and cannot be understood with logical thought or reason.[note 12]
According to Gombrich, this sutra may have been a warning against the tendency, "probably from the Buddha's day until now", to understand the doctrine of karma "backwards", to explain unfavorable conditions in this life when no other explanations are available. Gaining a better rebirth may have been, and still is, the central goal for many people. The adoption, by laity, of Buddhist beliefs and practices is seen as a good thing, which brings merit and good rebirth, but does not result in Nirvana, and liberation from samsāra, the ultimate goal of the Buddha.
According to the Buddhist tradition, the Buddha gained full and complete insight into the workings of karma at the time of his enlightenment.[note 13] According to Bronkhorst, these knowledges are later additions to the story, just like the notion of "liberating insight" itself.[note 14]
In AN 5.292, the Buddha asserted that it is not possible to avoid experiencing the result of a karmic deed once it has been committed.
In the Anguttara Nikaya, it is stated that karmic results are experienced either in this life (P. diṭṭadhammika) or in future lives (P. samparāyika). The former may involve a readily observable connection between action and karmic consequence, such as when a thief is captured and tortured by the authorities, but the connection need not necessarily be that obvious and in fact usually is not observable.
The Sammyutta Nikaya makes a basic distinction between past karma (P. purānakamma) which has already been incurred, and karma being created in the present (P. navakamma). Therefore, in the present one both creates new karma (P. navakamma) and encounters the result of past karma (P. kammavipāka). Karma in the early canon is also threefold: Mental action (S. manaḥkarman), bodily action (S. kāyakarman) and vocal action (S. vākkarman).
Various Buddhist philosophical schools developed within Buddhism, giving various interpretations regarding more refined points of karma. A major problem is the relation between the doctrine of no-self, and the "storage" of the traces of one's deeds, for which various solutions have been offered.
Early Indian Buddhism
The concept of karma originated in the Vedic religion, where it was related to the performance of rituals or the investment in good deeds to ensure the entrance to heaven after death, while other persons go to the underworld.
The concept of karma may have been of minor importance in early Buddhism. Schmithausen has questioned whether karma already played a role in the theory of rebirth of earliest Buddhism, noting that "the karma doctrine may have been incidental to early Buddhist soteriology." Langer notes that originally karma may have been only one of several concepts connected with rebirth.[note 15] Tillman Vetter notes that in early Buddhism rebirth is ascribed to craving or ignorance. Buswell too notes that "Early Buddhism does not identify bodily and mental motion, but desire (or thirst, trsna), as the cause of karmic consequences." Matthews notes that "there is no single major systematic exposition" on the subject of karma and "an account has to be put together from the dozens of places where karma is mentioned in the texts," which may mean that the doctrine was incidental to the main perspective of early Buddhist soteriology.
According to Vetter, "the Buddha at first sought, and realized, "the deathless" (amata/amrta[note 16]), which is concerned with the here and now.[note 17] Only after this realization did he become acquainted with the doctrine of rebirth." Bronkhorst disagrees, and concludes that the Buddha "introduced a concept of karma that differed considerably from the commonly held views of his time." According to Bronkhorst, not physical and mental activities as such were seen as responsible for rebirth, but intentions and desire.
The doctrine of karma may have been especially important for common people, for whom it was more important to cope with life's immediate demands, such as the problems of pain, injustice, and death. The doctrine of karma met these exigencies, and in time it became an important soteriological aim in its own right.
The Vaibhāśika-Sarvāstivāda was widely influential in India and beyond. Their understanding of karma in the Sarvāstivāda became normative for Buddhism in India and other countries. According to Dennis Hirota,
Sarvastivadins argued that there exists a dharma of "possession" (prapti), which functions with all karmic acts, so that each act or thought, though immediately passing away, creates the "possession" of that act in the continuum of instants we experience as a person. This possession itself is momentary, but continually reproduces a similar possession in the succeeding instant, even though the original act lies in the past. Through such continual regeneration, the act is "possessed" until the actualization of the result.
The Abhidharmahṛdaya by Dharmaśrī was the first systematic exposition of Vaibhāśika-Sarvāstivāda doctrine, and the third chapter, the Karma-varga, deals with the concept of karma systematically.
Another important exposition, the Mahāvibhāṣa, gives three definitions of karma:
action; karma is here supplanted in the text by the synonyms kriya or karitra, both of which mean "activity";
formal vinaya conduct;
human action as the agent of various effects; karma as that which links certain actions with certain effects, is the primary concern of the exposition.
The 4th century philosopher Vasubandhu compiled the Abhidharma-kośa, an extensive compendium which elaborated the positions of the Vaibhāṣika-Sarvāstivādin school on a wide range of issues raised by the early sutras. Chapter four of the Kośa is devoted to a study of karma, and chapters two and five contain formulations as to the mechanism of fruition and retribution. This became the main source of understanding of the perspective of early Buddhism for later Mahāyāna philosophers.
The Dārṣṭāntika-Sautrāntika school pioneered the idea of karmic seeds (S. Bīja) and "the special modification of the psycho-physical series" (S. saṃtatipaṇāmaviśeṣa) to explain the workings of karma. According to Dennis Hirota,
[T]he Sautrantikas [...] insisted that each act exists only in the present instant and perishes immediately. To explain causation, they taught that with each karmic act a "perfuming" occurs which, though not a dharma or existent factor itself, leaves a residual impression in the succeeding series of mental instants, causing it to undergo a process of subtle evolution eventually leading to the act’s result. Good and bad deeds performed are thus said to leave "seeds" or traces of disposition that will come to fruition.
In the Theravāda Abhidhamma and commentarial traditions, karma is taken up at length. The Abhidhamma Sangaha of Anuruddhācariya offers a treatment of the topic, with an exhaustive treatment in book five (5.3.7).
The Kathāvatthu, which discusses a number of controverted points related either directly or indirectly to the notion of kamma." This involved debate with the Pudgalavādin school, which postulated the provisional existence of the person (S. pudgala, P. puggala) to account for the ripening of karmic effects over time. The Kathāvatthu also records debate by the Theravādins with the Andhakas (who may have been Mahāsāṃghikas) regarding whether or not old age and death are the result (vipāka) of karma. The Theravāda maintained that they are not—not, apparently because there is no causal relation between the two, but because they wished to reserve the term vipāka strictly for mental results--"subjective phenomena arising through the effects of kamma."
In the canonical Theravāda view of kamma, "the belief that deeds done or ideas seized at the moment of death are particularly significant."
The Milindapañha, a paracanonical Theravāda text, offers some interpretations of karma theory at variance with the orthodox position. In particular, Nāgasena allows for the possibility of the transfer of merit to humans and one of the four classes of petas, perhaps in deference to folk belief. Nāgasena makes it clear that demerit cannot be transferred. One scholar asserts that the sharing of merit "can be linked to the Vedic śrāddha, for it was Buddhist practice not to upset existing traditions when well-established custom was not antithetic to Buddhist teaching."
The Petavatthu, which is fully canonical, endorses the transfer of merit even more widely, including the possibility of sharing merit with all petas.
Indian Yogācāra tradition
In the Yogācāra philosophical tradition, one of the two principal Mahāyāna schools, the principle of karma was extended considerably. In the Yogācāra formulation, all experience without exception is said to result from the ripening of karma.[web 9] Karmic seeds (S. bija) are said to be stored in the "storehouse consciousness" (S. ālayavijñāna) until such time as they ripen into experience. The term vāsāna ("perfuming") is also used, and Yogācārins debated whether vāsāna and bija were essentially the same, the seeds were the effect of the perfuming, or whether the perfuming simply affected the seeds. The seemingly external world is merely a "by-product" (adhipati-phala) of karma. The conditioning of the mind resulting from karma is called saṃskāra.[web 10]
The Treatise on Action (Karmasiddhiprakaraṇa), also by Vasubandhu, treats the subject of karma in detail from the Yogācāra perspective. According to scholar Dan Lusthaus,
Vasubandhu's Viṃśatikā (Twenty Verses) repeatedly emphasizes in a variety of ways that karma is intersubjective and that the course of each and every stream of consciousness (vijñāna-santāna, i.e., the changing individual) is profoundly influenced by its relations with other consciousness streams.
According to Bronkhorst, whereas in earlier systems it "was not clear how a series of completely mental events (the deed and its traces) could give rise to non-mental, material effects," with the (purported) idealism of the Yogācāra system this is not an issue.
In Mahāyāna traditions, karma is not the sole basis of rebirth. The rebirths of bodhisattvas after the seventh stage (S. bhūmi) are said to be consciously directed for the benefit of others still trapped in saṃsāra. Thus, theirs are not uncontrolled rebirths.
Nāgārjuna articulated the difficulty in forming a karma theory in his most prominent work, the Mūlamadhyamakakārikā (Fundamental Verses on the Middle Way):
If (the act) lasted till the time of ripening, (the act) would be eternal. If (the act) were terminated, how could the terminated produce a fruit? [subnote 3]
The Mūlamadhyamakavṛtty-Akutobhayā, also generally attributed to Nāgārjuna, concludes that it is impossible both for the act to persist somehow and also for it to perish immediately and still have efficacy at a later time.[note 18]
In Tibetan Buddhism, the teachings on karma belong to the preliminary teachings, that turn the mind towards the Buddhist dharma.
In the Vajrayana tradition, negative past karma may be "purified" through such practices as meditation on Vajrasattva because they both are the mind's psychological phenomenon. The performer of the action, after having purified the karma, does not experience the negative results he or she otherwise would have. Engaging in the ten negative actions out of selfishness and delusions hurts all involved. Otherwise, loving others, receives love; whereas; people with closed hearts may be prevented from happiness. One good thing about karma is that it can be purified through confession, if the thoughts become positive. Within Guru Yoga seven branch offerings practice, confession is the antidote to aversion.
East Asian traditions
Dōgen Kigen argued in his Shobogenzo that karmic latencies are emphatically not empty, going so far as to claim that belief in the emptiness of karma should be characterized as "non-Buddhist," although he also states that the "law of karman has no concrete existence."
Zen's most famous koan about karma is called Baizhang's Wild Fox (百丈野狐). The story of the koan is about an ancient Zen teacher whose answer to a question presents a wrong view about karma by saying that the person who has a foundation in cultivating the great practice "does not fall into cause and effect." Because of his unskillful answer the teacher reaps the result of living 500 lives as a wild fox. He is then able to appear as a human and ask the same question to Zen teacher Baizhang, who answers, "He is not in the dark about cause and effect." Hearing this answer the old teacher is freed from the life of a wild fox. The Zen perspective avoids the duality of asserting that an enlightened person is either subject to or free from the law of karma and that the key is not being ignorant about karma.
Nichiren Buddhism teaches that transformation and change through faith and practice changes adverse karma—negative causes made in the past that result in negative results in the present and future—to positive causes for benefits in the future.
Modern interpretations and controversies
Buddhist modernists often prefer to equate karma with social conditioning, in contradistinction with, as one scholar puts it, "early texts [which] give us little reason to interpret 'conditioning' as the infusion into the psyche of external social norms, or of awakening as simply transcending all psychological conditioning and social roles. Karmic conditioning drifts semantically toward 'cultural conditioning' under the influence of western discourses that elevate the individual over the social, cultural, and institutional. The traditional import of the karmic conditioning process, however, is primarily ethical and soteriological—actions condition circumstances in this and future lives."
Essentially, this understanding limits the scope of the traditional understanding of karmic effects so that it encompasses only saṃskāras—habits, dispositions and tendencies—and not external effects, while at the same time expanding the scope to include social conditioning that does not particularly involve volitional action.
Karma theory and social justice
Some western commentators and Buddhists have taken exception to aspects of karma theory, and have proposed revisions of various kinds. These proposals fall under the rubric of Buddhist modernism.
The "primary critique" of the Buddhist doctrine of karma is that some feel "karma may be socially and politically disempowering in its cultural effect, that without intending to do this, karma may in fact support social passivity or acquiescence in the face of oppression of various kinds." Dale S. Wright, a scholar specializing in Zen Buddhism, has proposed that the doctrine be reformulated for modern people, "separated from elements of supernatural thinking," so that karma is asserted to condition only personal qualities and dispositions rather than rebirth and external occurrences.
Loy argues that the idea of accumulating merit too easily becomes "spiritual materialism," a view echoed by other Buddhist modernists,[note 19] and further that karma has been used to rationalize racism, caste, economic oppression, birth handicaps and everything else.
Loy goes on to argue that the view that suffering such as that undergone by Holocaust victims could be attributed in part to the karmic ripenings of those victims is "fundamentalism, which blames the victims and rationalizes their horrific fate," and that this is "something no longer to be tolerated quietly. It is time for modern Buddhists and modern Buddhism to outgrow it" by revising or discarding the teachings on karma.
Other scholars have argued, however, that the teachings on karma do not encourage judgment and blame, given that the victims were not the same people who committed the acts, but rather were just part of the same mindstream-continuum with the past actors, and that the teachings on karma instead provide "a thoroughly satisfying explanation for suffering and loss" in which believers take comfort.

See also the Aggi-Vacchagotta Sutta, "Discourse to Vatsagotra on the [Simile of] Fire," Majjhima Nikaya 72,[web 8] in which the Buddha is questioned by Vatsagotra on the "ten indeterminate question," and the Buddha explains that a Tathagata is like a fire that has been extinguished, and is "deep, boundless, hard to fathom, like the sea".
^The understanding of rebirth, and the reappearance in accordance with one's deeds, are the first two knowledges that the Buddha is said to have acquired at his enlightenment, as described in Majjhima Nikaya 36.
^Bronkhorst is following Schmithausen, who, in his often-cited article On some Aspects of Descriptions or Theories of 'Liberating Insight' and 'Enlightenment' in Early Buddhism, notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36. It calls in question the reliability of these accounts, and the relation between dhyana and insight, which is a core problem in the study of early Buddhism. According to Tilmann Vetter, originally only the practice of dhyana, and the resulting calming of the mind may have constituted the liberating practice of the Buddha.
^Langer: "When I was searching the Sanskrit texts for material, two things become apparent: first, rebirth, central as it is to Indian philosophy, is not found in the earliest texts; and second, rebirth and karman do not appear to be linked together from the beginning. In fact, originally karman seems to have been only one of several concepts connected with rebirth, but in the course of time it proved to be more popular than others. One of these ‘other concepts’ linked with rebirth is a curious notion of ‘rebirth according to one’s wish’, sometimes referred to in the texts as kAmacAra. The wish — variously referred to in the texts as kAma or kratu — is directed to a particular form or place of rebirth and can be spontaneous (at the time of death) or cultivated for a long time. This understanding seems to have some affinity with the Buddhist notion that a mental effort, a positive state of mind, can bring about a good rebirth."
^Stanislaw Schayer, a Polish scholar, argued in the 1930s that the Nikayas preserve elements of an archaic form of Buddhism which is close to Brahmanical beliefs, and survived in the Mahayana tradition. According to Schayer, one of these elements is that Nirvana was conceived as the attainment of immortality, and the gaining of a deathless sphere from which there would be no falling back. According to Falk, in the precanonical tradition, there is a threefold division of reality, the third realm being the realm of nirvana, the "amrta sphere," characterized by prajna. This nirvana is an "abode" or "place" which is gained by the enlightened holy man. According to Falk, this scheme is reflected in the precanonical conception of the path to liberation. The nirvanic element, as an "essence" or pure consciousness, is immanent within samsara. The three bodies are concentric realities, which are stripped away or abandoned, leaving only the nirodhakaya of the liberated person. See also Rita Langer (2007), Buddhist Rituals of Death and Rebirth: Contemporary Sri Lankan Practice and Its Origins, p.26-28, on "redeath" (punarmrtyu).

^Rupert Gethin: "[Karma is] a being’s intentional 'actions' of body, speech, and mind—whatever is done, said, or even just thought with definite intention or volition"; "[a]t root karma or 'action' is considered a mental act or intention; it is an aspect of our mental life: 'It is "intention" that I call karma; having formed the intention, one performs acts (karma) by body, speech and mind.'"

Peter Harvey: "The movement of beings between rebirths is not a haphazard process but is ordered and governed by the law of karma, the principle that beings are reborn according to the nature and quality of their past actions; they are 'heir' to their actions (M.III.123)."
Damien Keown: "In the cosmology [of the realms of existence], karma functions as the elevator that takes people from one floor of the building to another. Good deeds result in an upward movement and bad deeds in a downward one. Karma is not a system of rewards and punishments meted out by God but a kind of natural law akin to the law of gravity. Individuals are thus the sole authors of their good and bad fortune."
Alexander Berzin: "In short, the external and internal cycles of time delineate samsara – uncontrollably recurring rebirth, fraught with problems and difficulties. These cycles are driven by impulses of energy, known in the Kalachakra system as "winds of karma." Karma is a force intimately connected with mind and arises due to confusion about reality."[web 2]
Paul Williams: "All rebirth is due to karman and is impermanent. Short of attaining enlightenment, in each rebirth one is born and dies, to be reborn elsewhere in accordance with the completely impersonal causal nature of one's own karman. The endless cycle of birth, rebirth, and redeath, is samsara." 
Ringu Tulku: "We create [karmic results] in three different ways, through actions that are positive, negative, or neutral. When we feel kindness and love and with this attitude do good things, which are beneficial to both ourselves and others, this is positive action. When we commit harmful deeds out of equally harmful intentions, this is negative action. Finally, when our motivation is indifferent and our deeds are neither harmful or beneficial, this is neutral action. The results we experience will accord with the quality of our actions."
Gethin: [R]ebirth in the lower realms is considered to be the result of relatively unwholesome (akuśala/akusala), or bad (pāpa) karma, while rebirth in the higher realms the result of relatively wholesome (kuśala/kusala), or good (puṇya/puñña) karma.
^Dargray: "When [the Buddhist] understanding of karma is correlated to the Buddhist doctrine of universal impermanence and No-Self, a serious problem arises as to where this trace is stored and what the trace left is. The problem is aggravated when the trace remains latent over a long period, perhaps over a period of many existences. The crucial problem presented to all schools of Buddhist philosophy was where the trace is stored and how it can remain in the ever-changing stream of phenomena which build up the individual and what the nature of this trace is."
Peter Harvey: "Karma is often likened to a seed, and the two words for karmic result, vipaka and phala, respectively mean 'ripening' and 'fruit'. An action is thus like a seed which will sooner or later, as part of its natural maturation process, result in certain fruits accruing to the doer of the action."
Ken McLeod: "Karma, then, describes how our actions evolve into experience, internally and externally. Each action is a seed which grows or evolves into our experience of the world. Every action either starts a new growth process or reinforces an old one as described by the four results.[subnote 1][web 5]
^Bhikkhu Thanissaro: "Unlike the theory of linear causality — which led the Vedists and Jains to see the relationship between an act and its result as predictable and tit-for-tat — the principle of this/that conditionality makes that relationship inherently complex. The results of kamma[subnote 2] experienced at any one point in time come not only from past kamma, but also from present kamma. This means that, although there are general patterns relating habitual acts to corresponding results [MN 135], there is no set one-for-one, tit-for-tat, relationship between a particular action and its results. Instead, the results are determined by the context of the act, both in terms of actions that preceded or followed it [MN 136] and in terms one’s state of mind at the time of acting or experiencing the result [AN 3:99]. [...] The feedback loops inherent in this/that conditionality mean that the working out of any particular cause-effect relationship can be very complex indeed. This explains why the Buddha says in AN 4:77 that the results of kamma are imponderable. Only a person who has developed the mental range of a Buddha—another imponderable itself—would be able to trace the intricacies of the kammic network. The basic premise of kamma is simple—that skillful intentions lead to favorable results, and unskillful ones to unfavorable results—but the process by which those results work themselves out is so intricate that it cannot be fully mapped. We can compare this with the Mandelbrot set, a mathematical set generated by a simple equation, but whose graph is so complex that it will probably never be completely explored."
^Sivaka Sutta (Samyutta Nikaya 36.21): "So any brahmans & contemplatives who are of the doctrine & view that whatever an individual feels — pleasure, pain, neither-pleasure-nor-pain — is entirely caused by what was done before — slip past what they themselves know, slip past what is agreed on by the world. Therefore I say that those brahmans & contemplatives are wrong."
Damien Keown: "Karma is not a system of rewards and punishments meted out by God but a kind of natural law akin to the law of gravity. Individuals are thus the sole authors of their good and bad fortune."
Peter Harvey states: - "The law of karma is seen as a natural law inherent in the nature of things, like the law of physics. It is not operated by a God, and indeed the gods are themselves under its sway. Good and bad rebirths are not, therefore, seen as "rewards" and "punishments", but as simply the natural results of certain kinds of action."
Dzongsar Khyentse: "[Karma] is usually understood as a sort of moralistic system of retribution—"bad" karma and "good" karma. But karma is simply a law of cause and effect, not to be confused with morality or ethics. No one, including Buddha, set the fundamental bar for what is negative and what is positive. Any motivation and action that steer us away from such truths as "all compounded things are impermanent" can result in negative consequences, or bad karma. And any action that brings us closer to understanding such truths as "all emotions are pain" can result in positive consequences, or good karma. At the end of the day, it was not for Buddha to judge; only you can truly know the motivation behind your actions."
Khandro Rinpoche states: "Buddhism is a nontheistic philosophy. We do not believe in a creator but in the causes and conditions that create certain circumstances that then come to fruition. This is called karma. It has nothing to do with judgement; there is no one keeping track of our karma and sending us up above or down below. Karma is simply the wholeness of a cause, or first action, and its effect, or fruition, which then becomes another cause. In fact, one karmic cause can have many fruitions, all of which can cause thousands more creations. Just as a handful of seed can ripen into a full field of grain, a small amount of karma can generate limitless effects."
Walpola Rahula states: "The theory of karma should not be confused with so-called 'moral justice’ or 'reward and punishment’. The idea of moral justice, or reward and punishment, arises out of the conception of a supreme being, a God, who sits in judgment, who is a law-giver and who decides what is right and wrong. The term 'justice’ is ambiguous and dangerous, and in its name more harm than good is done to humanity. The theory of karma is the theory of cause and effect, of action and reaction; it is a natural law, which has nothing to do with the idea of justice or reward and punishment. Every volitional action produces its effects or results. If a good action produces good effects and a bad action bad effects, it is not justice, or reward, or punishment meted out by anybody or any power sitting in judgment on your action, but this is in virtue of its own nature, its own law."
^Rupert Gethin: "From the Buddhist perspective certain experiences in life are indeed the results of previous actions; but our responses to those experiences, whether wished for or unwished for, are not predetermined but represent new actions which in time bear their own fruit in the future. The Buddhist understanding of individual responsibility does not mean that we should never seek or expect another’s assistance in order to better cope with the troubles of life. The belief that one’s broken leg is at one level to be explained as the result of unwholesome actions performed in a previous life does not mean that one should not go to a doctor to have the broken leg set."
^In the Tibetan tradition, a karmic action grows into four results: the result of full ripening, the result from what happened, the result from what acted, and the environmental result.
^Bhikkhu Thanissaro uses the Pali spelling for karma.
