There are 7 temples where Vidanga Murtis are worshipped. These are known as Saptha Vidanga Sthalams, located near Thanjavur. The processional deity in these temples is Thyagaraja or Somaskanda Murti. Each Murti has a special name and is known to perform a unique dance during processions. Legend has it that a Chola king by name Muchkunda Chakravarty helped Indra to win a battle. He wanted the Thyagaraja idol as a gift. Indra, not willing to part with the idol, made six more similar images and asked the king to choose one from them. With divine help, the king picked the original image. Indra, pleased with the king, gave him all the seven Thyagaraja idols. These were later installed in Thiruvarur, Nagapattinam, Thirunallar, Thirukkuvalai, Thiruvoimur, Vedaranyam and Thirukarayil.
Thiruvarur is located at a distance of 55 km from Thanjavur. The principal deity at this shrine is Sri Vanmikanathar, a Swayambu Lingam enshrined in an ant-hill. His consort is Somakulambigai. She is never taken out of the temple precincts. To the right of the sanctum is the shrine of Sri Thyagaraja.
The idol of Thyagaraja (Veedhi Vidangar) and that of His consort Kondi on an artistic Ratna Simhasan are very impressive. The processional deity is known to perform Asaba Natanam. The Spatika Lingam is kept in a golden box inside the shrine. The Nandi is in standing posture.

There is an inscription and sculptural representation of the story of King Manu Neethi Chola who ordered his son to be crushed under the wheels of a ratha or chariot because he killed a calf by driving his carriage negligently over it.
