8. Mahagauri
The eighth potency of mother Durga is Mahagauri. Her complexion is extremely fair. So it is compared to the conch, moon and Kunda flower. She is supposed to be eight year old always; all her garments and ornaments are also white. She has four arms. Her vehicle is a bullock. Her right upper hand is in the pose of allaying fear and right lower hand holds a trident in it. The left upper hand holds a Damaru and the lower one is in the pose of granting boon. Her appearance is very calm and serene.
In her Parvati form she practiced the severest possible penance with a desire to have Lord Shiva as her divine consort. She took a vow. Due to the severe penances her body became dark. Lord Siva was pleased in the end. He himself washed her body with the holy water of Ganga. Then her complexion changed to a shining one like a lightning flash. Since then she is known as Mahagauri.
