Traditionally, Kali is usually portrayed as being a woman with four hands, long flowing hair, and a dark complexion. With her left hand, she holds a kharga, or sword, and with her right hand, she holds the head of a demon she has slain. Abhaya Mudra is the symbol of protection, while Varada Mudra indicates blessings. Her mouth is protruding with her tongue and she is adorned with a garland made of severed necks. The iconography of her iconography shows her standing on her husband's thigh and his chest with one foot.
Kali Puja is observed across Bengal with huge marquees and the cleaning and decorating of temples dedicated to the goddess. Devi devotees worship Goddess Kali inside the marquees during Nishita Time of Amavasya by fasting throughout the day and worshiping her idols. Offerings to Goddesses include fruits, sweets, clothing, bhog, and hibiscus flowers. Bhhog and khichdi made from rice and lentil is an indispensable part of the Goddess' offerings.
