The story is set in the Durga Saptishati, two great demons called Chand and Mund, they we're from a great demon army who took orders from Shumbh and Anishumnh. Chand and Mund did great penance; they meditated for a great length until Lord Barhma appeared before them both. Brahama was pleased with them and asked them what wish they would like to be granted in reward for their penance. Chand and Mund both asked to be immortal, but Brahma stopped them and said, "Every being who is born on the earth must eventually die. That is the law of nature". Chand and Mund pondered, they both knew that they wanted to cause havoc and they thought women were defenceless. So by trying to out smart Braham they both agreed to ask that they would only be killed at the hands of the woman. Brahma was all knowing so he granted their wish. Chand and Mund were now incredibly powerful not only were they skilled in weaponry and possessed demonic powers, they had now the strength of the boon from Brahma. So they roamed the three worlds, until they saw Goddess Durga meditating upon a mountain. Goddess Durga was meditating in the form of Amba, she was incredibly beautiful and elegant. When Chand and Mund saw her they wanted to catch hold of her. But Chand and Mund were aware this was nor ordinary female. So they assembled their whole army around the mountain so they could overpower her. Amba was in strict meditation, but the sound of the demon army collecting around her awoke her. When Amba opened her eye she realised she was surrounded and in her anger her eyes became fiery and from her eyebrow appeared Kali. Kali's form came out screaming from Amba, filling the whole mountain with her shriek. Her body was black and dry. She was naked but covered only by tiger skin. Her eyes we're wide and her tongue was brandishing ferociously. Her neck was heavily decorated with a garland of severed heads and carried a bent sword (khhappar) in one hand. Her form was incredibly frightening and angry. She stood before Amba who gave her instructions to fight Chand and Mund.
