Only Love Me dearly.
Speak to me, as you would talk to your mother,
if she had taken you in her arms."
Maa Kali is the fearful and ferocious form of the mother goddess Durga. She assumed the form of a powerful goddess and became popular with the composition of the Devi Mahatmya, a text of the 5th - 6th century AD. Here she is depicted as having born from the brow of Goddess Durga during one of her battles with the evil forces. As the legend goes, in the battle, Kali was so much involved in the killing spree that she got carried away and began destroying everything in sight. To stop her, Lord Shiva threw himself under her feet. Shocked at this sight, Kali stuck out her tongue in astonishment, and put an end to her homicidal rampage. Hence the common image of Kali shows her in her mêlée mood, standing with one foot on Shiva's chest, with her enormous tongue stuck out.
Kali Puja is done to diminish the ego and all negative tendencies that hinder spiritual progress and material prosperity. Performed on the night of Kartik Amavasya, which falls in October/November, Kali Puja is an intense invocation to the fearsome goddess. The main purpose of the puja is to seek the help of the goddess in destroying evil - both in the outside world and within us.
The legend goes that long ago the demons, Shambhu and Nishambhu, disturbed the peace of Indra, the king of gods, and his empire (heaven). After extensive and endless battles, the gods lost all hope and the demons became stronger.
