Legend has it that in a test of strength between Adiseshan and Vayu, 5 gems are said to have gotten scattered from the head of Adisesha.
- A ruby stone landed at Tiruvannamalai,
- an emerald at Eengoimalai,
- a Blue sapphire at Potikai,
- a manikkam at Vaatpoki and
- a diamond rested here in this temple.
