Characteristics of Krita / Satya Yuga

Amongst the four eras, the Satya Yuga is the first and the most significant one. Knowledge, meditation, and penance hold special importance in this era. All the pillars of religion are present in totality. The average life expectancy of a human being in Satya Yuga is believed to be over 4000 years. During Satya Yuga, all people engage only in good, sublime deeds. Ashrams become devoid of wickedness and deceit. Natyam (such as Bharatanatyam), according to Natya Shastra, did not exist in the Satya Yuga "because it was the time when all people were happy".

...as described in the Mahabharata, a Hindu epic:

[...] there were no poor and no rich; there was no need to labour, because all that men required was obtained by the power of will; the chief virtue was the abandonment of all worldly desires. The Krita Yuga was without disease; there was no lessening with the years; there was no hatred or vanity, or evil thought; no sorrow, no fear. All mankind could attain to supreme blessedness. [...]

The maximum duration of life for human beings in Kali-yuga will become fifty years.
