Kali was first manifested when the Goddess Parvati knitted her brows in fury when the demon, Daruka, threatened the Gods. It was then that the three-eyed Kali first sprang forth from Parvati, fully armed, and immediately putting an end to Daruka. It is for this reason that Kali is considered an aspect of Parvati.
Other stories tell of how Kali fought and killed two demons. It was then, celebrating Her victory, that She drained the blood from their bodies and, drunk from the slaughter, She began to dance. Kali became overjoyed with the feel of their dead flesh under Her feet, and She continued to keep dancing, more and more wildly, until She finally realized that Her husband, Shiva, was underneath Her, and that She was dancing him to death.
Realizing this, Kali’s wildness did slow down, but only for a short while; it is believed that She will eventually continue Her dance and that when she does, it will bring an end to the world. Yet, her followers still believe that once faced and understood, Kali has the ability to free Her worshippers from all their fears. Once this occurs, then Kali metamorphasizes into another aspect, that of a loving and comforting Mother.
There is yet another version of Kali’s manifestation. The Gods were not able to kill the demon, Raktabija. Each drop of his blood that touched the ground turned into another Raktabija. Thus, every time he was struck, millions of his duplicates appeared all over the battlefield.
At this point the Gods were totally desperate, and they then turned to Shiva for help. Shiva, though, was so deep in meditation that he could not be reached. The Gods then turned to Shiva’s consort Parvati for help. The Goddess Parvati immediately set out to do battle with the demon, and it was then that She took the form of Kali.
Kali then appeared, with Her red eyes, dark complexion, gaunt features, hair unbound, and Her teeth as sharp as fangs. She rode into the midst of the battle on a lion, and it was only then that the demon Raktabija first began to experience fear.
Kali then ordered the Gods to attack Raktabija, while She spread Her tongue over the battlefield, covering it completely, and preventing even one drop of the demon’s blood from falling. In doing this, Kali prevented Raktabija from reproducing himself again, and the Gods were then victorious. Dolls of India
