Muniraj Datta was the son of Maharshi Atri and Anusuya. They lived in Saurashtra (Gujarat) and their Kuldevta is Sri Somanath. The fact that he was a Muni shows that his Ishta Devta was Vishnu. His most important works on Tantricism and the establishment of the Datta Parampara show his devotion to the Kuldevta Shiva. Thus, the worship of Shiva and Vishnu was encouraged in the Vedic times. In the form, which is advocated for worship, he has six arms with two each from Bramha, Vishnu and Shiva and is a composite mixture of all three divinities symbolizing A-U-M (Om in its transcendental form) Those people who do not have Guru in their lives can consider him their Guru.
