BRAHMA

Brahma, Cosmos, Time & Epoch:

Brahma presides over 'Brahmaloka,' a universe that contains all the splendors of the earth and all other worlds. In Hindu cosmology the universe exists for a single day called the ‘Brahmakalpa’. This day is equivalent to four billion earth years, at the end of which the whole universe gets dissolved. This process is called ‘pralaya’, which repeats for such 100 years, a period that represents Brahma's lifespan. After Brahma's "death", it is necessary that another 100 of his years pass until he is reborn and the whole creation begins anew.

Linga Purana, which delineates the clear calculations of the different cycles, indicates that Brahma's life is divided in one thousand cycles or ‘Maha Yugas’.
