The Mother's eighth form is known as "Mahagauri". She is mounted on an ox and has four hands. Her top right hand is rendering fearlessness and the hand below holds a trident. The top left hand holds a "Damru" and the hand below is in a gesture of giving a boon. To have Shiva as her husband she went through a rigorous penance in the form of "Parvati". As a result of this arduous meditation her complexion turned dark. Lord Shiva, pleased with the devotion of Parvati, bathed her in the holy water of the Ganges. As she bathed in the holy water she turned fair. From then onwards she became known as "Mahagauri". She is worshiped on the eighth day of the Durga puja. The devotee is benefited on all fronts as he worships the deity. Due to the Goddess's grace the devotee attains supernatural salvation, he is relieved from all his pains and fatigue and can set himself free from his previous sins. He is never faced with sorrow and poverty and never commits any sin. The devotee wins pure and endless virtue.
