The Dwadasa Jyotirlinga shrines or the 12 shrines enshrining Shiva in the form of a Jyotirlingam, have been held in reverence since time immemorial in the Indian system of beliefs. The southernmost of these is located at Rameswaram, while the northernmost is located in the snowy heights of the Himalayas at Kedarnath. These temples are closely linked with legends from the puranas and are rich in history and tradition.
