Basavanna was a 12th century philosopher, a Kannada social reformer and a renowned Shaivite. He is said to be an incarnation of Nandikeshwar by his followers. Basavanna is said to have found the Lingayata sect, a Shaivite sect which rejects the authority of the Vedas and downplays caste-system.
Since he's considered an incarnation of Nandikeshwar by his followers, I expect them to believe that he had performed certain miracles in his life. So are there any instances in his biographies of him having performed certain miracles?
