Kaalaratri – Mother Goddess's seventh form is "Kaalaratri". Her complexion is as dark as the night. Her cascading hair is let loose and she is seen wearing a garland that radiates light as bright as lightning. She is fearsome with her menacing three eyes, radiating fire. She is mounted on an donkey. She has four hands, of which, the top right hand is in a gesture of rendering boon to all. The other hand on her right is rendering fearlessness. The top left hand is holding an iron dagger and the other hand is holding a sickle. Although she has a menacing appearance, she always delivers favorable results and her devotees need not fear her manifestations.
She is worshiped on the seventh day of the Durga puja. Devi Kaalratri destroys the evil. If anyone whole-heartedly pleads of saving him from any impending danger, she protects him. As and when the Goddess is called, the evils instantaneously disappear from the place. By the Goddess's grace, the devotees overcome their fear of fire, water, animals and foes.
