Dussehra is the day to put an end to all the negativities and start fresh
Dussehra, also called Dasara or Vijayadashami, in Hinduism, holiday marking the triumph of Rama, an avatar of Vishnu, over the 10-headed demon king Ravana, who abducted Rama’s wife, Sita. The festival’s name is derived from the Sanskrit words dasha (“ten”) and hara (“defeat”). Symbolizing the victory of good over evil, Dussehra is celebrated on the 10th day of the month of Ashvina (September–October), the seventh month of the Hindu calendar, with the appearance of the full moon, an event called the “bright fortnight” (shukla paksha). Dussehra coincides with the culmination of the nine-day Navratri festival and with the tenth day of the Durga Puja festival. For many, it marks the beginning of preparation for Diwali, which occurs 20 days after Dussehra.
RamLeela depicts the entire story of how Ravana kidnaps Maa Sita and how Lord Rama valiantly fights against the evil king. On the tenth day i.e. on the day of Dussehra, huge effigies of Ravana are set on fire which signifies the victory of Lord Rama and his reunion with Maa Sita.
