Dussehra (Vijayadashami, Durgotsav) is a Hindu festival that marks the culmination of a 9 day period of festivities called Navratri (nine nights), with Dussehra being the 10th. Generally speaking, Dussehra is a celebration of the triumph of good over evil but is also the beginning of the harvest season in India and so people invoke the Mother Goddess to watch over the new harvest season and rejuvenate the fertility of the soil.
