How Kali Mata was born?

Kali Mata is believed to have been born from the forehead of Goddess Parvati or Gauri. When Mata Gauri became very angry at the misdeeds of demons and wrongdoers, Goddess Kali emerged from her forehead as a result of her uncontrolled anger. As she came into her ferocious avatar, she went on a rampage to kill the demons. Her wrath on the battlefield was so much that Lord Shiva had to intervene to stop her finally. He did this by lying down in front of her. When Goddess Kali stepped on him in her anger, she suddenly realized her mistake and calmed down. She is known for her fierce avatar with heads of demons hanging in her neck and a lolling tongue.
