Maha Navami, the ninth day of Sharad Navratri, is an observance grounded in devotion, myth and tradition. It recalls the final day of Goddess Durga"s battle with Mahishasura, the buffalo demon, before her ultimate victory on Vijaya Dashami. The day is seen as the culmination of Navratri devotion, symbolising the victory of righteousness over evil and preparing devotees to begin anew.
