Out of the five Kedars, three lies in Rudraprayag District.The term Kedar itself means a natural rock formation or glacial moraine. According to legend, Kedarnath, the chief seat of Panch Kedar, came into being during the period when the five Pandava brother were asked to seek Lord Shiva's blessing, purging them of the sin of killing their cousin brothers in the battle of Kurukshetra. Shiva disguised himself as a bull and started to plunge underground when he was spotted by the Pandavas. No wonder, the natural rock formation that is worshipped here resembles the rump of bull. The other two places where Shiva is worshipped take their appearance from different pats of his body - the navel at Madmaheshwar and the arm at Tungnath.
