As per mythology, the festival marks the victory of goddess Durga in her battle against the shape-shifting asura, Mahishasura. Thus, the festival epitomises the victory of good over evil, though it is also in part a harvest festival celebrating the goddess as the motherly power behind all of life and creation. Durga puja coincides with Navaratri and Dussehra celebrations observed by other traditions of Hinduism, in which the Ram lila dance-drama is enacted, celebrating the victory of Rama against Ravana, and effigies of Ravana are burnt.
