Vishnu as Veera Raghavar is the presiding deity of the Veera Raghavar temple. He is also called Vaidya Veera Raghavar, in view of his ailment curing abilities. In this temple people submit small metal sheets with a specific human organ engraved on them as a request to god to cure the illness or problems with those organs. It is believed that those suffering from incurable diseases are cured if they worship the presiding deity. Devotees come here for marriage, progeny, and for relief from hardships. The water in the tank is considered more sacred than that of river Ganga. A dip in the tank is believed to relieve the devotee from sins he committed in thought as well as action. Abishekam, the sacred ablution to the presiding deity is done only with sandalwood oil. The temple is considered the Vaishnavite temple equivalent of healing abilities of the presiding deity to that of the Vaitheeswaran, the presiding deity of the Saivite Vaitheeswaran Kovil. Thousands of devotees take a holy dip during new moon days and also pour molasses into the temple tank.
