Chaitra Navratri 2023 Day 7: The seventh day of Navratri is celebrated by worshipping Maa Kalratri, also known as Shubankari, who is believed to govern the planet Shani. The seventh form of goddess Durga is believed to be one of the fiercest forms, who removes kinds of negative energy, demons and ghosts upon her arrival. This manifestation of Goddess Durga also symbolises purity, divinity, and feminine power. Goddess Kalratri, as her name suggests means ‘kaal’ or death while ‘ratri’ means night. She drives away darkness and negativity and represents herself as a death of Kaal that appeared like a dark night for demons.
