The main Puja starts from "Shasthi" which is the sixth day after the new moon, when Devi Durga is welcomed with much fanfare and gusto. The face of the Durga is unveiled in the ‘Bodhon’ ritual.

On "Saptami" the image of the Goddess is infused with life. Early in the morning, the pran of the Devi is put inside the image after it is brought from a nearby river through the medium of a banana plant, called the ‘Kola Bou’. The Kola Bou ( wife of Ganesh), bathed and draped in a new yellow saree, resembles a newly wed bride.

Oshtumi universally accepted as the culminating point of the four day celebrations. It was on this day that Durga had killed Mahishasura. Devotees recite the mantras and offer flowers to Devi Durga (pushpanjali) and pray for her blessings. Rituals of animal sacrificesare held, but animals are now substituted with ‘chalkumro’ (type of pumpkin), cucumber and banana. The ritual of ‘Sandhipuja’ marks Sandhikkhan, the juncture between Oshtumi and Nabami. 108 ‘Deeps’ are lighted during ‘Sandhipuja’. At this time Devi Durga took the role of Devi Chamunda to kill the Mahishasura (the Buffalo Demon).

Nabami is the last day of the Durga Puja. The main attraction of Nabami is the Maha-Arati held in the evening. Nabami Bhog is the food offered to Devi Durga which is later distributed among the devotees.

Bijoya Dashami as this is called is the day when Goddess Durga accompanied with her children sets for Kailash, her husband’s abode.With a heavy heart the image of the Devi is immersed in a river (Bisharjan), and people bid a sorrowful farewell to the Mother Goddess, and the earnest wait begins for yet another year. ‘Sindur Khela’ (vermilion game) is a major event of Dashami. Married women apply vermillion to each other and greet each other with sweets. It is in the evening when Goddess Durga is immersed. Bengalis greet each other with Bijoya greetings and men follow the customary ‘Kolakuli’ (embrace each other). Bijoya is a special ritual whereby peace and good relations are reaffirmed. Families exchange sweets and people embrace each other, vowing brotherhood. Bijoya continues till the next new moon, when Kali Puja is held.
