It is believed that Parvathi, the consort of Shiva, came here after marrying him in the Himalayas. Parvathi got her menstrual period for 28 days. Bhagavathy is thus considered a reincarnation of Sati. Another variant of the same legend indicates that sage Agasthya, who could not witness the sacred marriage of Shiva and Parvathi was visited by the pair after the marriage. Since Parvathi was in her menstrual period, she waited for 28 days to give darshan to the sage.
