It is believed that Goddess Durga killed the demon king Mahishasura after nine nights of battle, which is celebrated as Vijayadashami on the next day after Maha Navami to mark the victory of good over evil. Devotees worship all nine forms of Goddess Durga during the nine-day festival of Sharad Navratri 2022 and on Navami, the goddess is worshipped as Mahishasuramardini.
