The legend says Khara Maharshi had done the Prathishta as single Idol of Sree Mahadeva, giving the place the name Ottasekharamangalam-meaning place where single Siva exists. The divine power of the Idol was so high that even a bird couldnt fly over the Shrine. So after years,the Idol was divided into two-Thekkedam and Vadakkedam and the Thekkedam is the Moola Sthana.
