Seventh Avatar of Durga: Maa Kalratri is worshipped on the Seventh Day of Navaratri. She is dark and black like night; hence she is called Kalratri. HER hair is unlocked and she possesses three eyes and four hands, two of her right hands are in the mudras of giving and protecting. HER vahana is a faithful donkey. She is the destroyer of darkness and ignorance. She spills out fire from her nostrils. She holds a sharp sword in her left hand and a hook weapon in her lower hand. As she blesses her devotees with prosperity, she is also called Shubhamkari.
