On the eighth day of Navaratri, devotees worship the Maha Gauri form of Goddess Durga. She is an avatar of Devi Parvati, divine consort of lord Shiva.
Unlike Kalratri, who is ferocious, Maha Gauri is calm and compassionate. She is depicted in white clothes and mounted on a bull. It is believed that anyone who worships the goddess gets relief from all the sufferings in life.
You can chant this mantra to seek Maa Maha Gauri’s blessings:

महागौरी शुभं दद्यान्महादेवप्रमोददा॥
