It is believed by the local tribals and villagers that Saint Mahadeshwara was an incarnation of Lord Shiva who came down to earth to destroy an evil king, Shravanasura. He is believed to have performed many miracles and he rode on a tiger. His legend is recounted as an epic in 7 parts by the locals in the Janapada folk style. The story bears a resemblance to the ancient Indian Epic Ramayana. Historically, Saint Mahadeshwara is believed to have lived in the 15th century. It is believed that he came here to perform meditation. People believe he is still continuing his Tapas inside the temple in the form of a Linga. The Janapada singers of his legend belong to the Kuruba community. The singing group are called as 'Devaara Guddha' or God's child, also as 'Kamsaleyavaaru', since they always keep bronze cymbals with them which are called Kamsaale. They are initiated into the art form when very young and are expected to lead a disciplined life. The shrine has a major segment of the nearby land and also possesses the lands in adjacent villages. The temple was constructed by a wealthy landlord of the Kurubha tribe, Junje Gowdha.
