The presiding deity, Sri Vaidyanathaswamy, is hailed as the healer of all ills. The Lord came here as a Vaidya and cured Angaraha of leprosy. Among the Navagrahas, Angaraha is worshipped here with great reverence. Hence this shrine is also known as Angaraha Kshetra. Jatayu, Rig Veda, Muruga and Surya worshipped the Lord here. The temple is located in Vaitheeswaran Koil near Sirkali, in Tamil Nadu.
