Defeating the Buffalo Demon
Hindu tradition records that the demon Mahishasura, through austerities, won the boon of being unkillable "by any male god or mortal," and grew ever more rampant, the gods helpless; so they gathered their weapons and powers into one and brought forth Durga. Riding a tiger into battle, Durga fought for nine days and nights and on the tenth slew Mahishasura — a victory seen as a classic symbol of "good triumphing over evil."
