Matsya Avatar or the fish incarnation is the first of the ten avatars of Vishnu, the Supreme Lord. The eighth canto of Srimad Bhagavatam describes the pastimes of ‘Matsya avatar’ in great detail. In addition, Matsya Purana also glorifies His wonderful pastimes. Five thousand years ago, Parikshit Maharaj inquired about the Matsya avatar from Srila Sukadeva Goswami. Sri Sukadeva Goswami explained how the Supreme Lord incarnates in this world millennium after millennium in order to protect the cows, brahmanas, religious principles, spiritual knowledge, etc. Although the Supreme Lord appears sometimes as a human being and sometimes as a lower animal, He nonetheless always stays transcendental. Sukadeva Goswami glorified Matsya avatar and described how in the previous millennium (Svayambhuva Manvantara), while Lord Brahma was asleep, the water of devastation flooded the three worlds, only leaving Brahmaloka and a few other higher planets untouched. As Brahma took rest, the demon Hayagriva tried to steal the Vedic knowledge that emanated from Brahma’s mouth. The Supreme Lord Vishnu, then assumed the form of ‘Matsya avatar’ (fish incarnation), as everything was inundated by water, and rescued the Vedas by killing the demon.
