Vama and Dakshina Kali
Dakshina Kali, the peaceful form of Kali. She puts her right ‘dakshina’ foot forward, thus the name.
When Kali puts her left foot foward, on the other hand, she becomes the fierce and destructive Vama Kali, worshipped by very few. The sight of Vama Kali is enough to kill a regular follower, it is said. Thus a peaceful, motherly form and a fierce form.
