Manali has a pre-historic legend behind its name. Vaivasvata, the seventh incarnation of Manu, the first creation according to Hindu mythology, found a tiny fish in his bathing water. The fish told him to look after it with devotion, for one day it would do him a great service. The seventh Manu cared for the fish until it grew so huge that he released it into the sea. Before departing, the fish warned Manu of an impending deluge when the entire world would be submerged and bade him to build a seaworthy ark. When the flood came, Matsya (fish), the first avatar of Lord Vishnu, towed Vaivasvata and the Seven Sages to safety. As the waters subsided, the seventh Manu's ark came to rest on a hillside and the place was named Manali after him.
