The Manu and the Fish Story

Floods are seen as something periodic which happens anyway. Humans have tried to attribute morality to it, that we establish culture and plunder nature. But really that's not a dominant thought in Indian mythology. The flood doesn't care for anyone. Everybody will be watched away. So the Manu and the Fish story is like a time when things collapse. And he carries the Vedas with him. Basically the whole idea is the Vedas survive the flood.
