The first Manu was Svāyambhuva Manu. His two daughters, namely Ākūti and Devahūti, gave birth to two sons, named Yajña and Kapila respectively. Because Śukadeva Gosvāmī had already described the activities of Kapila in the Third Canto, he now described the activities of Yajña. The original Manu, along with his wife, Śatarūpā, went into the forest to practice austerities on the bank of the river Sunandā. They practiced austerities for a hundred years, and then Manu, in a trance, formed prayers to the Supreme Personality of Godhead. Rākṣasas and asuras then attempted to devour him, but Yajña, accompanied by his sons the Yāmas and the demigods, killed them. Then Yajña personally took the post of Indra, the King of the heavenly planets.
