The seventh among the Shakti Roopas is Goddess Kaalratri. The destroyer of darkness and ignorance, Kaalratri is the enemy of darkness. Goddess Kaalratri is extremely frightening to look at but she is always auspicious in effect. This is why she is otherwise known as Subhankari (doing well).She has dark skin color with disheveled hair. A necklace flashing like lightning adorns her neck. She has three eyes, which are circular in the form like cosmic egg, which always eject rays. Terrible flames appear when she inhales or exhales air through her nostrils. Her vehicle is a donkey. Her raised right hand always seems to grant boons to all and sundry. Her right lower hand is in the pose of allaying fears. Her left upper hand holds a thorn-like weapon made of iron and in the lower left hand there is a dagger. Her worshipper does not fear fire, water, wild beings, enemy or night. Goddess Kaladatri destroys the Danava, Daitya, Raksasa, Bhuta, Preta and all other evil spirits.On the seventh day of Navratra, the mind of the worshiper reaches Sahasrara Chakra. For such a striver, the door of all Siddhis of the universe start opening. On this day, all the sins and obstacles in the way of worshipers are completely destroyed.During Durga Puja, the most important food which is prepared and offered to Durga Maa is Khichdi or Khichuri. It is made with basmati rice, moong daal and lots of vegetables cooked in ghee or clarified butter and garnished with cashew and raisins. It is prepared on Ashthami and is consumed only after the Puja is over.
