All of the ardent Shiva devotees know that Lord Shiva's abodes are one of the most scenic and captivating places of all and almost all are high on the difficulty level to reach.
Having said that Tungnath is the highest of his abodes in the world towering close to 12000 feet. Tungnath is one of the 5 kedars the others being Rudranath, Madhyameshwar, Kalpeshwar and Kedarnath.
The most famous legend of the panch kedar or 5 kedars as we say it is that sage Vyas Rishi advised the Pandavas that since they were culpable of slaying their own relatives (Kauravas, their cousins) during the Mahabharata war or Kurukshetra war, their act could be pardoned only by Lord Shiva. Consequently, the Pandavas went in search of Shiva who was avoiding them since he was convinced of the guilt of Pandavas. In order to keep away from them, Shiva took the form of a bull and went into hiding in an underground safe haven at Guptakashi, where Pandavas chased him. But later Shiva’s body in the form of bull’s body parts rematerialized at five different locations that represent the "Panch Kedar" where Pandavas built temples of Lord Shiva at each location, to worship and venerate, seeking his pardon and blessings. Each one is identified with a part of his body; Tungnath is identified as the place where the bahu (hands) were seen: hump was seen at Kedarnath; head appeared at Rudranath; his navel and stomach surfaced at Madhyamaheshwar; and his jata (hair or locks) at Kalpeshwar.
