There are many incarnations of the Supreme Personality of Godhead. Manu, the manu-putrāḥ (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 Uttānapāda, the demigods created by Dakṣa, and the ṛṣis like Marīci were all partial incarnations of the Lord during the reign of Svāyambhuva Manu. During that time, the incarnation of the Lord as Yajña took charge of ruling the heavenly planets. The next Manu was Svārociṣa. The Manus and the sages and demigods are further described in the following eleven verses.
