According to Hindu beliefs, the demon kingRavana worshipped Shiva at the current site of the temple to get the boons that he later used to wreak havoc in the world. Ravana offered his ten heads one after another to Shiva as a sacrifice. Pleased with this, Shiva descended to cure Ravana who was injured. As he acted as a doctor, he is referred to asVaidhya (“doctor”). From this aspect of Shiva, the temple derives its name.
