Vijayadashami is the final day of Durga Navaratri. On this day Durga Visarjan or Udvasan is performed. There is a popular legend associated with Vijaya Dashami tells us about another ritual ‘Shami Puja.
Legend of Vijayadashami and Shami Puja:
Apart from the story of Lord Ram and Ravan about Vijayadashami, another legend is mentioned in Mahabharata. Pandavas underwent aranyavaas (exile) for a period of time. Pandavas kept their weapons on Shami tree and went to exile incognito. At the moment when they hid their weapons on the tree they performed puja to the tree to guard the weapons safely.
At the end of the year, they returned and found their weapons safe. They again worshipped Shami tree for guarding their weapons. They also performed Durga Puja to guide them in the battlefield to beat Kauravas.
In the battlefield, Pandavas were succeeded in defeating Kauravas and since then the day is celebrated as Vijayadashami. And the Shami Puja became a main ritual during Vijayadashami.
On this day, leaves of Shami tree are exchanged among friends and relatives as gold. They wish their friends and relatives to get success in every aspect of life.
