Purukutsa had a son by Narmadá named Trasadasyu, whose son was Sambhúta, whose son was Anarańya, who was slain, by Rávańa in his triumphant progress through the nations. The son of Anarańya was Prishadaśwa; his son was Haryyaśwa; his son was Sumanas; his son was Tridhanwan; his son was Trayyáruńa; and his son was Satyavrata, who obtained the appellation of Triśanku, and was degraded to the condition of a Cháńd́ála, or outcast. During a twelve years' famine Triśanku provided the flesh of deer for the nourishment of the wife and children of Viswamitra, suspending it upon a spreading fig-tree on the borders of the Ganges, that he might not subject them to the indignity of receiving presents from an outcast. On this account Viśwámitra, being highly pleased with him, elevated him in his living body to heaven.
