Rajashekhara Dasa
From the book “Chaurasi-kosa Vraja Mandala Parikrama”:
In this temple are the Deities of Lord Narasingha, Lord Varaha, and Lord Narayana, and it is believed that these were the Deities worshiped by Nanda Maharaja. Nanda was already worshiping the Deities of Lord Varaha and Lord Narayana, but on the advice of the family priest Gargamuni, Nanda Baba began worshiping Lord Narasingha Deva in order to protect Krishna from the attacks of demons. The Deity of Lord Narayana is no longer being worshiped due to damage inflicted on it by marauding Mohammedan soldiers during the dark period of the Islamic conquests of India.
