स तु सत्यव्रतो राजा ज्ञानविज्ञानसंयुतः ।
विष्णोः प्रसादात्कल्पे ऽस्मिन्न् आसीद्वैवस्वतो मनुः ॥ ५८ ॥
visnoh prasadat kalpe 'sminn
sah-he; tu-indeed; satyavratah-Satyavrata; raja-the King; jnana-vijnana-samyutah-enlightened in full knowledge and its practical use; visnoh-of Lord Visnu; prasadat-by the mercy; kalpe asmin-in this period (ruled by Vaivasvata Manu); asit-became; vaivasvatah manuh-Vaivasvata Manu.
King Satyavrata was illuminated with all Vedic knowledge by the mercy of Lord Visnu, and in this period he has now taken birth as Vaivasvata Manu, the son of the sun-god.
Srila Visvanatha Cakravarti Thakura gives his verdict that Satyavrata appeared in the Caksusa-manvantara. When the Caksusa-manvantara ended, the period of Vaivasvata Manu began. By the grace of Lord Visnu, Satyavrata received instructions from the second fish incarnation and was thus enlightened in all spiritual knowledge.
