Navratri means (Nav=Nine ,Ratri=Nights) Festival of nine Nights. This festival is one of the most prominent festivals of Hinduism dedicated to chiefly Mother Durga an incarnation of Goddess Parvati, the consort of Lord Shiva. This is the most pious and pure time in the complete Hindu calendar. These nine nights are dedicated to the three main goddesses of Hinduism - Parvati, Lakshmi and Saraswati. During Navratri, Durga is worshipped under different names: Shailaputri, Brahmacharini, Chandraghanta, Kushmanda, Skandamata, Katyayani, Kalaratri, Mahagauri, and Siddhatri. She is also worshipped as Mahakali for killing the demons, Madhu and Kaitabha, who, for thousands of years troubled Vishnu. When they stole the holy Vedas from the hands of Brahma, who was sitting on a lotus stalk arising from Vishnu’s navel, Vishnu invoked the goddess and she killed the two demons. She is also worshipped as Chamunda for killing the demons Chunda and Munda; as Nanda for predicting the death of Kansa (Kamsa) at the hands of Krishna; as Sakhambari for protecting the world from famine; as Kumari, the eternal virgin and so on.
