In the Indian creation myth it is believed that world is created, destroyed, re-created in eternally repetitive series of cycles. It moves from one Maha Yuga to the next, and each Maha Yuga contains four yugas each worse than the last one.

This egg will contain the seeds of all forms of life on earth before the flood. Ass the world drowns the egg will safely flood over the ocean. After that Vishnu will sleep for 1,000...
