In some versions, he is the son of Vaivasvata Manu (formerly the Emperor Satyavrata of Dravida), one of the two central characters along with the Lord Matsya incarnation of Lord Vishnu in the Matsya Purana. He is born to Manu after the deluge which sends the King's ship to the top of the Malaya Mountains in the Dravida country.
