 It was then that Vishnu, revealing himself, informed the king of an all-destructive deluge which would be coming very soon.The king built a huge boat which housed his family, saptarishi, nine types of seeds, and animals to repopulate the earth, after the deluge would end and the oceans and seas would recede.At the time of deluge, Vishnu appeared as a horned fish and Shesha appeared as a rope, with which the king fastened the boat to the horn of the fish.
