He was given the boon of turning anyone to ashes if he/she touched his/her head. However, after receiving blessings and power, Bhasmasura wanted to try it with the Lord. It was then that Vishnu intervened, in the form of a woman named Mohini. She distracted Bhasmasura with her dance and eventually led him to touch his head. Tirumogur is said to be the place where Lord Vishnu, in the form of Lord Vishnu, put an end to the threat of the demon Bhasmasuran.
According to another legend, when the Asuras and the Devas churned the ocean, a fight broke out over the right to Amuda, the sacred pot of nectar. During the war in which the Asuras overthrew the Devas, they sought the help of Vishnu. To help them, the Lord took the form of Mohini to charm the demons and eventually gave them an empty pot. It is said that this event took place in Tirumogur.
