In this temple, the presiding deity is Dharbaranyeswarar and is believed to have been made of Dharba(Grass). However, the worship is centered around the Lord Saneeswarar(Planet Saturn) and hence it is one of the Navagraha temples in Tamilnadu. The tradition is to worship Lord Saniswarar before entering the inner sanctum of Lord Siva.
