Maa Mahagauri is the eighth form of Goddess Durga. She is worshipped on the eighth day of Navratri. In Hindu mythology it is believed that Goddess Mahagauri has the power to fulfill all desires of her devotees.
Maa Mahagauri has four arms, her lower right hand holds a trishul, the upper right hand is in the mudra of allaying fear. While her lower left hand is in a pose of granting boons to Her devotees and she is holding a damaru in Her upper left hand.
She is usually depicted in a white or green sari riding a bull. The legend has it that Maa Mahagauri liberated the world from all evil forces.
Her name Mahagauri means extremely white as she was very beautiful and white in color.
Mythology has many tales when it comes to Maa Mahagauri. It is believed that Kali/Durga incarnated as Parvati who was beautiful yet had a black complexion and once, she was teased by Mahadev as Kali.
Infuriated by this remark, she began a great penance to please Lord Brahma and get the fair complexion, in this way her name Mahagauri got justified.
