"Vaisampayana continued, 'Having thus talked and laughed with each other, they separated, Devayani returning to the palace with the knowledge imparted to her by Sarmishtha. And, O king, Yayati also begot on Devayani two sons called Yadu and Turvasu, who were like Indra and Vishnu. And Sarmishtha, the daughter of Vrishaparvan, became through the royal sage the mother of three sons in all, named Drahyu, Anu, and Puru.
