Mahishasuran, armed with his boon, began to commit atrocities and murders on the earth and terrorised people. Fearing his wrath, people ran away to far away places.

The Devas seeing the atrocities committed by Mahishasuran came to the conclusion that only a divine power could kill him and approached Chandikadevi (Mahishasuramardhini) pleading to put an end to Mahishasura who was misusing the boon given by Lord Brahma. Chandikadevi set out on her mission and killed Mahishasura in a duel, on earth.

Mahishi, daughter of Karamba, brother of Ramban undertook a severe penance in order to take revenge on the Devas, who were responsible for the death of her brother. Lord Brahma appeared and offered to confer on Mahishi any boon except that of immortality. Mahishi asked Lord Brahma to bless her with a boon by which nobody, except the son created out of the union of Vishnu (Hari) and Shiva (Haran), would be able to kill her. Lord Brahma gave the boon and Mahishi went to Devaloka and started harassing the Devas.The Devas incurred the wrath of Durvasa Muni who cursed them. On the advice of Lord Mahavishnu that this curse could be removed only by administering Amrutham taken from Palazhi, the devas took it from the Palazhi, but the Asuras snatched it from them.
