During the churning of the ocean, the Divine serpent Adisesha was bearing the whole weight of earth. As the weight grew due to the sins committed by the wicked, he could not carry the excess weight and felt exhausted. He visited Mount Kailash and begged Lord Shiva to bless him with the adequate energy needed to do his job.
The Lord promised him the energy to hold the earth with a single head (Adiseaha has 1000 heads). Adiseaha, with the blessings of Lord Shiva came to this part of Kumbakonam where one leaf of Vilwa fell from the nectar pot. He installed a Linga here and worshipped the Lord.
As Nagaraja the king of snakes worshipped the Lord here, He is praised as Nageswarar.The place where the Vilwa fell from the nectar pot floating through floods, was called Vilwa Vanam. Lord is also praised as Vilwa Vanesar, Padala Beeja Nathar, Madanthai Bagar and Selva Piran.
