King Satyavrata was illuminated with all Vedic knowledge by the mercy of Lord Viṣṇu, and in this period he has now taken birth as Vaivasvata Manu, the son of the sun-god.
PURPORT
Śrīla Viśvanātha Cakravartī Thākura gives his verdict that Satyavrata appeared in the Cākṣuṣa- manvantara . When the Cākṣuṣa- manvantara  ended, the period of Vaivasvata Manu began. By the grace of Lord Viṣṇu, Satyavrata received instructions from the second fish incarnation and was thus enlightened in all spiritual knowledge.
