In India there are three major categories of pilgrimage temples dedicated to the god Shiva: Jyotir Lingams; Svayambhu Lingams, and Bhuta Lingams. Located in five south Indian temples, the Bhuta Lingams are said to be places where Shiva manifested himself as the natural elements. The temples and their respective elements are Chidambaram: ether, Sri Kalahasti: wind, Tiruvanaikka/Jambunath: water, Kanchipuram: earth, and Tiruvanamalai: fire. Chidambaram is also associated with the heart, Tiruvanaikka with the stomach, and Tiruvanamalai with the chest.
The Arunachaleswar Shiva temple in Tiruvanamalai (Tiruvanamalai is the Tamil word for the Sanskrit Arunachala), situated at the foot of the Arunachala hill, is one of the largest (25 acres) and oldest temples in all of south India. The era of its founding is unknown; the complex grew over several millenia and the large towers, called gopurams, were erected between the 10th and 16th centuries. The tallest gopuram is over 60 meters tall and has 13 stories. The central temple enshrines images of Shiva as Lord Annamalai and his consort as Unnamalai. Every year during the Hindu month of Kartikai (November-December), the great Deepam festival is held to celebrate Shiva's manifestation as the light of Arunachala. For ten days the whole city of Tiruvanamalai is alive with celebration, processions, dancing and singing. On the final day of the festival, the eve of the full moon, a huge beacon fire is lighted atop the hill in commemoration of the fire left by Shiva. Many thousands of pilgrims flock to this exciting festival from all over southern India. Arunachala hill is considered a miraculous healing place, especially for ailments of the lungs and barrenness in women. The hill of Arunachala is also a symbol of spiritual knowledge and several great sages have lived here, including Arunagirinathar, the author of the Tiruppugal, and Sri Ramana Maharshi (1879-1950).
