Srikalahasti Temple is located in the town of Srikalahasti, in the state of Andhra Pradesh, India. It is one of the most famous Shiva temples in South India, and is said to be the site where Kannappa, one of the 63 Saivite Nayanars, was ready to offer both his eyes to cover blood flowing from the Siva linga before the Lord Siva stopped him and granted him mukti.
Sri Kalahasti temple, situated 36 km away from Tirupati is famous for its Vayu deva temple, which is the only shrine for the God of Wind in India. Constructed in the 12th century by the Chola king, Rajendra Chola, Vayu is incarnated as Lord Shiva and worshipped as Kalahasteeswara.
This ancient temple dedicated to Lord Siva is one of the five Panchabhootha stalams (temples celebrating Lord Siva as the embodiment of the five primary elements), air (wind) being the element in this case; the other elements being water at (Thiruvanaikaval), fire at (Annamalaiyar Temple), earth at (Ekambareswarar Temple) and space at (Chidambaram Temple) that Siva embodies.
There is a lamp inside the inner sanctum that is constantly flickering despite the lack of air movement inside. The air-linga can be observed to move even when the priests close off the entrance to the main deity room, which does not have any windows. One can see the flames on several ghee lamps flicker as if blown by moving air. The linga is white and is considered Swayambhu, or self-manifested.
Kalahasti is surrounded by two sacred hills. The Durgamba temple is on the northern hill. On the south hill there is the shrine of Kannabeswara, in memory of the Sage Kannappa, who offered his eyes to the Lord. There is also a temple dedicated to Lord Subramanya on one of the surrounding hills.
The main linga is untouched by human hands, even by the priest. Abhisheka (bathing) is done by pouring a mixture of water, milk, camphor, and panchamrita. Sandal paste, flowers and the sacred thread are offered to the utsava-murti, not the main linga.
