Dānu, a Hindu primordial goddess, is mentioned in the Rigveda, mother of the Danavas. The word Danu described the primeval waters which this deity perhaps embodied. In the Rigveda (I.32.9), she is identified as the mother of Vrtra, the demonic serpent slain by Indra. In later Hinduism, she becomes the daughter of Daksha and the consort of Kasyapa. As a Hindu goddess, Dānu has 2 temples in Bali, Indonesia: Pura Ulun Danu Temple on Lake Bratan, Bali and Ulun Danu Batur, near Penelokan.
