The 'Matsya Purana' related to the Vaishnava sect is a very important mythology in terms of fasting, festival, pilgrimage, charity, rajdharma and architectural arts.
God tells Matsya Manu that during the Holocaust period, by taking your boat in my horn and taking it safely and creating the creation. They recognize God's "fish avatar" and praise them. Manu protects himself by fishery god during the Holocaust period. Then there is a human creation by Brahma. But without seeing any result of that creation, Daksh Prajapati develops the creation from the mathuni-universe.
