According to Jain legends, Rana Raj Singh I of Mewar once visited this temple to offer prayer. He noticed a white hair while putting saffron to the idol. Upon question about the hair, the temple priest replied that the hair was from the moustaches of Lord Mahavira. Following, this Rana insisted to see moustache. The temple priest fasted for three days and pleased with this the protecting deity showed moustache on the face of the idol. When Rana uprooted the moustache, blood oozed out of the spot. Following this Rana became a staunch devoutee of the Mahavira and the idol was named Mucchal Mahavir, or the Mahavir who had a moustache.
