Vashishta Gufa is an ancient cave where the human son of Lord Brahma, Sage Vashishta meditated. A legend states that the sage was extremely depressed after losing all his children and decided to commit suicide, but River Ganga didn't allow him to die. He, therefore, decided to stay and meditate in the cave. The cave houses a Shivalinga and is maintained by the Purishottamanand Society.
