This temple is known as Kudanthai Karonam and located near Potramarai Kulam. The Sikkam (threads) around the Amirthakalasam (the nectar pot) fell here and took a shape of Linga and hence known as Sikkeshwarar (Sutra Natha—Lord of the Thread). Once Chandra (Moon god) due to Guru’s (Brahaspathi) curse arrived in Kumbakonam and worshipped Lord Shiva Sikkeshwarar. He created a holy water source for the worship, this tank was known as Chandrapushkarani (does not exist now).
