Jambukeshwar Thiruvanaikaval

Jambukeshwar Thiruvanaikaval is one of the Pancha Bhoota Sthalas — five temples in South India where Shiva is worshipped as one of the five classical elements. Here he is appu (water). The Appu Liṅga is constantly half-submerged in spring water that emerges continuously from the sanctum floor.
