The battle raged on for 9 days and nights and on the 10th day Goddess Durga gained victory over the demon Mahishasura. According to Hindu beliefs, Dusserah or Vijayadashmi was the day, the demon was finally defeated and killed by Devi Durga, thereby regaining the balance of the cosmos.
Maha Navaratri is a festival celebrated on 5th of October to honor and worship Durga and her nine incarnations. On all the ten days, believers attend Devi temples to pray and offer pujas to please the Goddess. Sometimes the idol of the Goddess is draped, adorned with flowers, placed upon a raised platform and secured to large vehicles. The Goddess is then escorted to different areas in the town or city by priests, so that the believers can offer their pujas and seek blessings.
Mahishasura was an asura who achieved penance from God Shiva. He prayed to God Shiva to grant him the boon of being unkillable by any God or man. With the increased power, Mahishasura and his followers grew arrogant and triumphed over Indra creating havoc in all the worlds. Defeated, Indra requested the ‘Great Trinity’ (Trimurti Gods) for justice. The supreme Gods created the warrior Goddess Durga to eliminate the asuras.
