Mbh 12.231.5b — Mahabharata

(The total duration, therefore, of the Krita yuga is four thousand and eight hundred years of the deities). As regards the other yugas, the duration of each gradually decreases by a quarter in respect of both the substantive period with the conjoining portion and the conjoining portion itself. (Thus the duration of the Treta is three thousand years and its morning extends for three hundred years and its evening for three hundred). The duration of the Dwapara also is two thousand years, and its morning extends for two hundred years and its evening also for two hundred. The duration of the Kali yuga is one thousand years, and its morning extends for one hundred years, and its evening for one hundred.[873] These periods always sustain the never-ending and eternal worlds. They who are conversant with Brahma, O child, regard this as Immutable Brahma. In the Krita age all the duties exist in their entirety, along with Truth. No knowledge or object came to men of that age through unrighteous or forbidden means.[874] In the other yugas, duty, ordained in the Vedas, is seen to gradually decline by a quarter in each. Sinfulness grows in consequence of theft, untruth, and deception. In the Krita age, all persons are free from disease and crowned with success in respect of all their objects, and all live for four hundred years. In the Treta, the period of life decreases by a quarter. It has also been heard by us that, in the succeeding yugas, the words of the Vedas, the periods of life, the blessings (uttered by Brahmanas), and the fruits of Vedic rites, all decrease gradually. The duties set down for the Krita yuga are of one kind. Those for the Treta are otherwise. Those for the Dwapara are different. And those for the Kali are otherwise. This is in accordance with that decline that marks every succeeding yuga. In the Krita, Penance occupies the foremost place. In the Treta, Knowledge is foremost.
