Kedarnath temple Shivalingam is pyramid shaped and hence is unique among Shiva temples.

Kedarnath ji is highest among the 12 Jyotirlingas. This ancient and magnificent temple is located in the Rudra Himalaya range. This temple, over a thousand years old is built of massive stone slabs over a large rectangular platform. Ascending through the large grey steps leading to the holy sanctums we find inscriptions in Pali on the steps. The present temple was built by Adi Shankaracharya. Outside the temple door a large statue of the Nandi Bull stands as guard. A conical rock formation inside the temple is worshipped as Lord Shiva in his Sadashiva form. Kedarnath is amongst the holiest pilgrimages for the devout Hindus. It is set amidst the stunning mountain scape of the Garhwal Himalayas at the head of the Mandakini River. Kedar is another name of Lord Shiva, the protector and the destroyer. Shiva, the embodiment of all passions love, hatred, fear, death and mysticism which are expressed through his various forms.

Kedarnath temple Shivalingam is pyramid shaped and hence is unique among Shiva temples. After the Mahabharat war of 4000 BC, Pandavas were guilty of over drive. They had no honour left and were having nightmares during sleep. It was Lord Krishna himself who advised them to seek the blessing of Lord Shiva. By getting Darshan of the form of light, the Pandavas were absolved of their sins. Bhima had fought with bull form of Shiva with maces, so he was struck with remorse. He massaged Shivas body with ghee. In memory of this event, Kedarnath Ji is massaged with ghee even today. It's mentioned in scriptures that by visiting Kedarnath Ji , sorrows do not come even in dreams.
