The four shrines of Chota Char Dham in Garhwal are very important for Hindu pilgrims because they are at four sources of the river Ganga. However, the source of the Rishi Ganga tributary is inaccessible. Nanda Devi, the Goddess of Bliss, lived on the top of the mountain that is named after her and which is where the Seven Rishis were driven by the demons before they finally became seven stars in the sky. Nanda Devi left her mountain to live with her husband Shiva on Mount Kailash in Tibet but once a year, in October, she returns and this is a time of celebration for pilgrims.
