Frustrated at the reincarnating powers of the demon Raktabeej, Durga turns black with fury and goes berserk as Kali, beheading everything in her path. Lest her unbridled fury obliterate all creation, Vishnu hits upon a brainwave and asks Shiv, Kali's husband, to lie down in her path. Oblivious of what she's stepping on, Kali stumbles upon him and her bloodlust is interrupted. Her embarrassment is the only thing that brings her back to sanity and thus - the universe is saved (woo hoo)...
