Kaśyapa chanced to meet his wife Diti, and through his powers (of asceticism) made her young again. On being questioned by Kaśyapa, Diti said that she wanted to be mother of such a progeny as would kill Lord Indra and conquer all the Devas. Kaśyapa promised to beget such a child from her womb when the sage Âpastamba performed a putreṣṭi sacrifice. The sage Âpstamba eventually began to perform the sacrifice.—30-34.
