The son of Agni named Svarocisa became the second Manu. His several sons were headed by Dyumat, Susena and Rocismat.

There are many incarnations of the Supreme Personality of Godhead. Manu, the manu-putrah (the sons of Manu), the king of the heavenly planets, and the seven great sages are all partial incarnations of the Supreme Lord. Manu himself, his sons Priyavrata and Uttanapada, the demigods created by Daksa, and the rsis like Marici were all partial incarnations of the Lord during the reign of Svayambhuva Manu. During that time, the incarnation of the Lord as Yajña took charge of ruling the heavenly planets. The next Manu was Svarocisa. The Manus and the sages and demigods are further described in the following eleven verses.
