The Thyagarajar Temple at Tiruvarur is famous for the ajapa thanam(dance without chanting), that is executed by the deity itself. According to legend, a Chola king named Mucukunta obtained a boon from Indra(a celestial deity) and wished to receive an image of Thyagaraja Swamy(presiding deity, Shiva in the temple) reposing on the chest of reclining Lord Vishnu. Indra tried to misguide the king and had six other images made, but the king chose the right image at Tiruvarur. The other six images were installed in Thirukkuvalai, Nagapattinam, Tirukarayil, Tirukolili, Thirukkuvalai and Tirumaraikadu. All the seven places are villages situated in the river Cauvery delta. All seven Thyagaraja images are said to dance when taken in procession(it is the bearers of the processional deity who actually dance).
