To fight and overcome the natural hazards common in this region, psychologically rural people are very dependent on the strength of religious beliefs and supernatural powers. Hindus and Muslims worship the same deities in spite of belonging to different religions. The practice of worshipping trees, snakes, tigers and other animals is common. The Goddess of the forest is ‘Bonbibi’ who is worshipped in almost every village. Bonbibi is probably synonymous with the Hindu Goddess ‘Bonodevi’; the former became more acceptable with the advent of Muslim rule in lowerBengal.
Bonbibi the lady of the forest, also Bondevi, Bondurga and Byaghra devi is a guardian deity of the forests worshipped by both the Hindu and the Muslim residents of the Sundarbans (spread across West Bengal state in eastern India and Bangladesh). She is worshipped mostly by the fisher, honey-collectors and the woodcutters before entering the forest for protection against the attacks from the tigers. It is believed that the demon king, Dakkhin Rai (the lord of the south), an arch-enemy of Banbibi actually appears in the disguise of a tiger and attacks human beings.
