She is worshipped on the eighth day of Navaratri. Her power is unfailing and instantly fruitful. As a result of her worship, all sins of past, present and future get washed away and devotees get purified in all aspects of life. Maha Gauri is intelligent, peaceful and calm. Due to her long austerities in the deep forests of the Himalayas, she developed a dark complexion. When Lord Shiva cleaned her with the water of the Ganges, her body regained its beauty and she came to be known as Maha Gauri, which mean extremely white. She wears white clothes, has four arms, and rides on a bull. Her right hand is in the pose of allaying fear and her right lower hand holds a trident. The left upper hand holds a ‘damaru’ (a small rattle drum) and the lower one is in the pose of granting boons to her devotees.
