Kali is a ferocious form of the Divine Mother, who sent her Shakti, the Mother Gauri, to free the gods from the dominion of the demonic forces Shumbh and Nishumbh. Kali is the goddess of time and of the transformation that is death. Kali also is the Kundalini energy that paralyses the attachments produced by the solar and lunar currents (both demons).
The Hindu goddess Kali is the first of the ten Mahavidyas - the others are Tara, Shodashi, Bhuvaneshwari, Bhairavi, Chinnamasta and Dhumavati, Matangi, Kamala and Bagla Mukhi. Therefore Kali is also known as Adya, the firstborn. In the ignorant ones she creates fear, while for others Kali removes the fear of death.
