When he grew up, he intended to destroy the whole universe as a revenge for the slaughter of his family. So, he did austere penances. Seeing that the world was about to come to an end, the Pitrs came down to him. They prayed to him to change his mind. They said that it was their own decision of dying at the hands of the Kshatriyas, for they were bored of their long lives. But they could not resort to suicide, for through suicide, they would reach Naraka and not Svarga, and hence they had hid all their wealth underground to enrage the warriors. After their death, they had attained Svarga. Hearing this, Aurva took the decision to not destroy the universe. As suggested, he threw the fire of his penance into the ocean, which consumed water in the form of a horse's mouth, named Vadavamukha, giving rise to the Vadavagni, the submarine fire.
