In Bangladesh, Pujas take place all year round. Durga Puja above all. It is not possible to say exactly when Durga Puja was introduced in East Bengal. The date of Durga Puja in Malkhanagar can be traced back to the architecture of the puja buildings, the shape of the bricks and the spice of the masonry. Judging from these, it is estimated that Durga Puja started from 1750, i.e. seventy years after building of Seghara. Devdas Basu Thakur himself built temples in some houses but it cannot be said that in all the houses Durga Puja was started at the same time.

The preparation of Durga Puja would start a month ago. The masters of the house would decide whom to invite from which village. Accordingly, invitations were sent through messengers. This was the custom for some time before the post office facility came into the picture. Thereafter the invitations began to be sent out by post.

In the Puja building, the preparations for making idols would start. Many of the potters were subjects (Proja) of Basu Thakurs’. The potters used to make idols in the house of Basu Thakurs for generation after generation. At first, the structural framework was made with straw, bamboo and clay. It changed as time passed by. The arrangement of the idols in the Puja of this family was Ganesh and Swaraswati on the left side of Durga and Kartik and Lakshmi on the right. In general, it is just the opposite. Before Sasthi Puja, kirtan (A special type of singing group) group would go around the village singing Agamni (Arrival ) songs. Along with the Hindus, people from the Muslim community would also sing these Agamni (Arrival ) songs with their separate song group. For each member of these Hindu and Muslim singing group, five seer(one seer=930 gms) of rice per head was allotted from each house, and in proportion to that pulses, vegetables, oil, salt and spices. And dakshina (tips) was one rupee.

Worship was performed in every house with great devotion according to the scriptures. The family priests used to worship. Those who helped the priests also did this for generations. They were called Mondopi. They received free lands to stay provided to them by the Basu Thakurs’. Those who made the 'Kalabau"/"Nabapatrika" and take it to the puja bulidings also received free to stay.

On the night of Mahaashtami, Kali Puja was done in the puja buildings. This Kali Puja is a symbol of Mahishardini Durga as Bhadrakali. The custom of this puja is that, it start on the night of Astomi and has to complete within that night itself, following which idol Immersion has to be done before the next sunrise. Till date this tradition is followed. In Malkhanagar, the day of the Nabami puja was the day for the sacrifice (Boli) festival. Upto 1910 - 1911, buffaloes were sacrificed as per ritual. After that goat and pumpkin sacrifice began. On the Saptami and Astomi, male goats were sacrificed in the puja houses. On the Nabomi,the elders of the house, the sons, daughters, son-in-laws, grandsons and granddaughters all used to gather in the puja building at the Pub Er Bari. Musicians from all the puja buildings would come to this puja building along with their drums, brass and clarinet. From this place the sacrifice (Boli) festival began. Then everyone would march with the musicians and celebrate this festival in one house after another starting from Nazir's Bari.

The sacrifice (Boli) festival stopped at Boro Bari from 1916. At the time of the sacrifice on the Saptami of that year, the sacrifice was not done through one stroke of the sword which is considered to be an indication of special misfortune. After this incident priests of special classes were called by Basu Thakurs’. They performed special compensatory rituals according to the scriptures, but it did not help. Lalit Kumar Basu Thakur of this house died on the next day i.e. on Astomi in Kashi (Benaras). Goat sacrifice was banned at the house of the Basu Thakurs’ from the following year. From then onwards till now as a token gesture of the earlier custom only pumpkin sacrifice is being done every year.

Aarti dance was performed in the evening on the three days of Puja from Saptami to Nabami. Tarapada, Haripada and Devpada, the three sons of Bimalacharan Chakraborty of the village, used to dance with ten or twelve incense pots (dhunuchis). Jotu Bhai of that house was the best performer in the Aarti dance. His actual name was Phanibhushan Chakraborty. He used to dance with a total of 16 incense pots(dhunuchi). Besides, he had seven pitchers on his head. He used to dance with all these. People from far and wide used to come to see his Aarti dance.

Dasomi is the next day after Nabomi. At dawn of the day Dasomi, two Puti fish would be kept at the doorstep of every house by the fisherman and a pot of yoghurt would be left by the milkman. In the afternoon, the elders and the boys of the house would put a drop of yoghurt on their tongues and see the Puti fish before they left the house for Dashmi Idol Immersion Procession (Bisarjan Jatra). Once the Boron (ceremonial leave-taking of Maa Durga and other idols performed by the women of Basu Thakur family and other women of the village) was over, subjects (Proja) would carry the idol on their shoulders from the Puja building to the canal in the north of the village and put it on the cargo boat. Then the cargo boats with the idol would go to Taltala Ghat.

From Dhaleshwari river, the canal touched the north side of Taltola Bazar and Malkhanagar village and extended to Srinagar in the west. The idol-laden cargo boats would be parked at the entrance of the canal. Dashami was a famous event at Taltala. The custom of keeping boats was also orderly. First the boat of the Basu Thakurs’. Then the idol of Kailash Pal's house. Then others would follow. There used to be forty boats in a row. The boats were arranged in such a manner that one could go easily from one end to the other. The elders of Malkhanagar used to sit in one of their boats. From there they maintained the discipline of Dashmir Mela (Fairs). Mela (Fairs) were held all over the grounds at Taltala Bazar and Post Office.

After the partition, the format of the festival changed. Up until 1950, Durga Puja was performed in three or four houses of Basu Thakurs in the village. When they also moved to Calcutta, the Durga Puja of Basu Thakurs’ in Malkhanagar stopped.

Dr Atindranath Basu Thakur was the person who came up with the idea of gathering all the Basu Thakurs, who lived in Calcutta at that time, to create a forum. From that idea emerged Malkhanagar Sammilani. In 1959, the Basu Thakurs created the Malkhanagar Sammilani in Calcutta and started Durga Puja in an organized manner.The first Durga Puja in Calcutta began at Basant Kumar Basu Thakur's house at 115 Harish Mukherjee Road, Kolkata - 700025. Worship was held there till 1967. In1968 it moved to Devkumar Basu Thakur's house at 26B Chandra Mondal Lane, Kolkata-700033. Puja continued their till 1981. In 1982, it was relocated to Sajal Basu Thakur's house at 6B Fern Place. Kolkata -700019. Later, worship was held at the house of Subir Kumar Ghosh, the youngest son of Sarbani Ghosh, who was the eldest daughter of Sukumar Basu Thakur of Naya Bari. Thereafter worship was held at the house of Apurba Kumar Ghosh, son-in-law of Malkhanagar, in his Ganguly Bagan’s house. Then it was shifted to Nrupen Banerjee's house at 1/14 Ramgarh,Kolkata – 700047, After that it has shifted to a house at 31 G Block, Bagajatin, next to Arunachal club., Kolkata - 700086 where it continued till 2016.
