At the end of the Dwapara Yuga, in the Sura Sura war, Indra was afflicted with Brahmma Hathi Dosham. To liberate himself from this, he undertook penance and invoked the blessings for Lord Vishnu.
He was directed to install 5 Narayana Idols in this region to liberate himself from his dosham. Thondanur Yoga narasimha Temple is the first and the oldest of the Pancha Narayana Kshetrams. The others in this region being – Cheluva Narayana at Melkote, Keerthi Narayana at Thalakkad, Veera Narayana at Gadag and Sowmya Narayana at Belur.
Belief is that one will attain Vaikunta Moksham if he visited the Pancha Narayana Kshetram.
