A Yuga (Sanskrit: युग, lit. 'age'), in Hinduism, is a large period of time as it relates to the past, present or future.[1] It is mostly used to describe one of the four dharmic ages⁠—Satya Yuga, Treta Yuga, Dvapara Yuga or Kali Yuga⁠—or a cycle of the four ages, Chatur Yuga.[2][3]

Depending on context, it can refer to one of the seasons, generations, reigns, kalpas (days of Brahma), stages of creation (manifest, maintain, unmanifest), or 1,000 year periods.[4]


The archaic form of the Sanskrit word "yuga" is "yug". Other forms are "yugam", "yugānāṃ" and "yuge". In Latin, "juga" or "jug" are used from "jugum" meaning "yoke", used to connect two oxen (e.g. cali-juga = kali-yuga).[5] The word "yuga", as well as "yoga", are derived from Sanskrit: युज्, romanizedyuj, lit. 'to join or yoke', believed to be derived from Proto-Indo-European language: yeug, 'to join or unite'.

Yuga characteristics

There are a total of four yugas : Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga, each having 1/4th less duration and dharma than the previous (Satya most, Kali least). The descending yugas see a gradual decline[citation needed] of dharma, wisdom, knowledge, intellectual capability, lifespan, emotional and physical strength.

Within a yuga are Sandhis, or a starting Sandhya and ending Sandhyansa, both lasting 1/10th the main part of the yuga.[citation needed] Most of the characteristic changes can occur in these Sandhyas and Sandhyansas, especially if that change is from Kali Yuga to Satya Yuga (two extremes)[citation needed].

  • Satya Yuga (Krita Yuga, "the age of truth", or "hindu golden age") : the first and best yuga. It is the age of truth and perfection. This yuga has no crime, and all humans are kind and friendly. The Krita Yuga is so named because there is one religion, and all men are saintly : therefore they are not required to perform religious ceremonies. Humans are long living, powerfully built, honest, youthful, vigorous, erudite and virtuous. The Vedas are one. All mankind can attain to supreme blessedness. There is no agriculture or mining, as the earth yields those riches on its own. Weather is pleasant, and everyone is happy. There is no religious sect. There is no disease, decrepitude, or fear of anything[citation needed]. Virtue reigns supreme. Human stature is 21 cubits (33 ft, 6 inches). Average human lifespan is 100,000 years[citation needed].
  • Treta Yuga : this is the second yuga in chronological order. However, "treta" means the "third". In this age, virtue diminishes slightly. At the beginning of the age, many emperors rise to dominance and conquer the world. Wars become frequent and weather begins to change to extremities. People become slightly diminished, compared to their predecessors. Agriculture, labour and mining become existent[citation needed]. There are 3 quarter virtues and 1 quarter sin. Normal human stature is 14 cubits (22 ft, 4 inches). Average human lifespan is 10,000 years[citation needed].
  • Dvapara Yuga : this is the third yuga in order. However, "dvapara" means "two"/"second". In this age, people become tainted with qualities, and aren't as strong as their ancestors. Diseases become rampant. Humans are discontent and fight each other. Vedas are divided into four parts. People still possess characteristics of youth in old age. Average lifespan of humans is around a few centuries[citation needed]. There are 1 half virtue and 1 half sin. Normal human stature is 7 cubits (11 ft, 2 inches). Average human lifespan is 1,000 years[citation needed].
  • Kali Yuga : the final age. It is the age of darkness and ignorance. People stop following dharma, and lack virtue. They become slaves to their passions and are barely as powerful as their earliest ancestors in the Satya Yuga. Society falls into disuse and people become liars and hypocrites. Knowledge is lost and scriptures are diminished. Humans eat forbidden and dirty food. The environment is polluted, water and food become scarce. Wealth is heavily diminished. Families become non-existent[citation needed]. There is 1 quarter virtue, and 3 quarter sins. Normal human stature is 3.5 cubits (5 ft, 3 inches). Average human lifespan is 100 years[citation needed].
