But hear now the brief (description of) the duration of a night and a day of Brahman and of the several ages (of the world, yuga) according to their order.
They declare that the Krita age (consists of) four thousand years (of the gods); the twilight preceding it consists of as many hundreds, and the twilight following it of the same number.
In the other three ages with their twilights preceding and following, the thousands and hundreds are diminished by one (in each).
These twelve thousand (years) which thus have been just mentioned as the total of four (human) ages, are called one age of the gods.
But know that the sum of one thousand ages of the gods (makes) one day of Brahman, and that his night has the same length.
Those (only, who) know that the holy day of Brahman, indeed, ends after (the completion of) one thousand ages (of the gods) and that his night lasts as long, (are really) men acquainted with (the length of) days and nights.
At the end of that day and night he who was asleep, awakes and, after awaking, creates mind, which is both real and unreal.
Mind, impelled by (Brahman’s) desire to create, performs the work of creation by modifying itself, thence ether is produced; they declare that sound is the quality of the latter.
But from ether, modifying itself, springs the pure, powerful wind, the vehicle of all perfumes; that is held to possess the quality of touch.
Next from wind modifying itself, proceeds the brilliant light, which illuminates and dispels darkness; that is declared to possess the quality of colour;
And from light, modifying itself, (is produced) water, possessing the quality of taste, from water earth which has the quality of smell; such is the creation in the beginning.
The before-mentioned age of the gods, (or) twelve thousand (of their years), being multiplied by seventy-one, (constitutes what) is here named the period of a Manu (Manvantara).
The Manvantaras, the creations and destructions (of the world, are) numberless; sporting, as it were, Brahman repeats this again and again.
In the Krita age Dharma is four-footed and entire, and (so is) Truth; nor does any gain accrue to men by unrighteousness.
In the other (three ages), by reason of (unjust) gains (agama), Dharma is deprived successively of one foot, and through (the prevalence of) theft, falsehood, and fraud the merit (gained by men) is diminished by one fourth (in each).
(Men are) free from disease, accomplish all their aims, and live four hundred years in the Krita age, but in the Treta and (in each of) the succeeding (ages) their life is lessened by one quarter.
The life of mortals, mentioned in the Veda, the desired results of sacrificial rites and the (supernatural) power of embodied (spirits) are fruits proportioned among men according to (the character of) the age.
One set of duties (is prescribed) for men in the Krita age, different ones in the Treta and in the Dvapara, and (again) another (set) in the Kali, in a proportion as (those) ages decrease in length.
In the Krita age the chief (virtue) is declared to be (the performance of) austerities, in the Treta (divine) knowledge, in the Dvapara (the performance of) sacrifices, in the Kali liberality alone.
