Durga Puja is a the nine-day festival, which is celebrated in West Bengal in the honour of goddess Durga. Festivities commence on the first night in the month of Ashwin (September/October). Goddess Durga is considered as the destroyer of the demon 'Mahisasura'. She is also considered as Shakti, the cosmic energy that animates all beings. She is also called Sarba Jananani, a goddess for all, and is shown riding her mount, the lion. On Vijayadashami or the tenth day, a clay image of the goddess is immersed in the sea or river. This immersion or
visarjan symbolises Durga's return to her husband Shiva on the conclusion of her annual visit to her parental home. The nine days of pooja are synonymous with the Navratris, during which Rabindra Sangeet, dances and various programmes form a part of the celebrations. A number of delicacies are prepared such as luchi, aloo dum, chana dal, baigun bhaja, payesh, baiguni and halwa.
