Summary: Ayudha Puja is the most significant aspect of Dussehra celebrations. Dussehra or Navaratri, is a journey from darkness to light. One should become reverential towards the instruments that you employ - and the most fundamental and basic instrument is your own body and your own mind. Once you establish a certain distance between you and your body and mind, that signifies victory. So, the last day is celebrated as vijadashmi or the day of victory.
