All of the YUGAS, or ages, in the Indian tradition, refer to throws in an ancient game of dice. Krita (“the one that made it!”) is the best throw—a 4.
The Krita Yuga, which like all ages has appeared an infinite number of times and will return an infinite number of times, is also called Satya Yuga, or the age of truth. It is 1,728,000 years long. In Krita Yuga the highest virtue is said to be MEDITA-TION. In this age, BRAHMA is god. Eternal DHARMA is said to have all its four feet in this age, while in the others it progressively has three, two, and one. In the Krita age there is no distinction between the best and worst of creatures. Their life, happiness, and attractiveness are all equal. They are also free of sorrow, completely good, and enjoy solitude, rather than crowds. They are devoted to MEDITA-TION, active in spiritual restraints and austerities, and act always without self-interest. They are always joyful and have no permanent homes, but live in the mountains or by the oceans.
