Kali became popular as a powerful goddess with the composition of the text Devi Mahatmya in the 5th and the 6th century AD. The legend goes that two demons, Shambhu and Nishambhu disturbed the peace of Lord Indra. After endless battles when the gods failed, they sought help from Lord Shiva and Parvati. The gods sought protection of Maa Durga or Shakti. Kali was born out of Durga’s brow as Kal Bhoi Nashini.

Along with her two escorts, Dakini and Jogini, she was meant to destroy all evils and the growing cruelty of demons. It is believed that Kaali was so much engrossed in the killing spree that she went on killing everything within her sight. To stop this, Lord Shiva, threw himself under her feet. She was so shocked with this act of Lord Shiva, that she stuck her tongue out in disbelief. Hence we have the common image of Kali standing with her feet on Shiva’s chest and her tongue out.
