The eight manifestation of Goddess Durga is Maha Gauri, worshipped on the eighth day of Navaratri. Maha Gauri is a manifestation is of Goddess Parvati. When Parvati observed a hard sacrament to obtain Lord Shiva in the forest of Himalayas, she developed a dark complexion. When Lord Shiva accepted her great devotion, he washed the body of Parvati with water of “pure Gange”s or “Ganga” and her body regained its beauty. She came to be recognized as “Maha Gauri”, meaning “extremely white” and became prominent as the consort of Mahadev(Lord Shiva). Devi Gauri is bright, peaceful and calm and her beauty glows like sparkling White Pearl. She is depicted sitting on a bull (Vrishabha) and has four arms. Her right hand is in the pose of alleviating fear and her right lower hand holds a trident. She holds a ‘damaru’ (a small drum) in her right hand while the lower one grants boons to her devotees. Elucidation of her grace is infinite. Maha Gauri is the true Goddess of kindness and morality.
MahaGauri should be worshipped with the chant of following Mantra:
या देवी सर्वभूतेषु माँ गौरी रूपेण संस्थिता।
नमस्तस्यै नमस्तस्यै नमस्तस्यै नमो नम:।।
