Durga Puja, the biggest festival in Bengal starts on September 26 this year. The celebration continues for the next five days culminating with the idol immersion ceremony on Dasami. Vijayadasami marks the end of Durga Puja, and is celebrated as triumph of goddess Durga over the demon Mahisasura to help restore Dharma. On this day the idols of goddess Durga are moved from its place for immersion into the river and she is believed to return to the abode of her husband. After the process of immersion is over, people enjoy delicious dinner and sweets.
