This lingam was buried under the roots of an Arjuna tree for a long time. Hence we can see the impressions of the roots of the tree on the body of the lingam. During the Mahabharatha time Pandavas had lived in the areas around Dharapuram a nearby town. It is a belief that during that period, Arjuna had worshipped this Linga. This is one of the reason's why the deity has been named Arjuneswarar.
