During the war between the Kauravas and Pandavas, their own kith and kin got killed. In order to absolve themselves of this sin, the Pandavas wanted to seek blessings of Shiva who was away in Kailasa. They saw Shiva in Himalayas who hid from them. "Oh, Lord, You have hidden yourself from our sight because we have sinned. But, we will seek You out somehow. Only after we take your Darshan would our sins be washed away. This place, where You have hidden Yourself will be known as Guptkashi and become a famous shrine.” From Guptakashi (Rudraprayag), the Pandavas went ahead they reached Gaurikund in the Himalayas valleys.

Bhima caught hold of the bull by its tail and hind legs. But the bull-formed Shiva disappeared into the ground to later reappear in parts, with the hump raising in Kedarnath, the arms appearing in Tunganath, the nabhi (navel) and stomach surfacing in Madhyamaheshwar, the face showing up at Rudranath and the hair and the head appearing in Kalpeshwar. The Pandavas pleased with this reappearance in five different forms, built temples at the five places for worshipping Shiva. The Pandavas were thus freed from their sins. It is also believed that the fore portions of Shiva appeared at Pashupatinath Nepal. Panch Kedar are Sri Kedarnath, Sri Tungnath, Sri Rudranath, Sri Madhyamaheshwar and Sri Kalpeshwar. The Kedarnath is part of Chota Char Dhams, 'the small four abodes or pilgrimage centers of the Garhwal Himalayas. the other three dhams are the Badrinath, Yamunotri and Gangotri. By visiting Kedarnath sorrows do not come even in dreams.
Jai Sri Kedarnath ~ Jai Shiva Shankara!
