A debate arose between Lord Shiva and Mother Parvathi as to who was more powerful among them. Shiva claimed he was, but Shakti was too voracious in her defence on the debate to establish her claim. Angry Shiva cursed her to become an Ugra kali. Realizing her haste and violent argument, Shakti begged Shiva for a remedy. Lord Said, Devas and men will be subjected to the atrocities of demons shortly. You, as Ugra Kali will destroy the demons and protect Devas and men. Then, You come to Thillai (now Chidambaram) and perform penance on me.
