The concept of Nava-durga is extremely popular during Navratri. Navratri refers to the nine nights that lead to the celebration of Vijayadashmi. The Goddess is worshipped in nine forms. The nine forms are Shailaputri, Brahmacharini, Chandraghanta, Kushmanda, SkandaMata, Kaatyayani, Kalaratri, Mahagauri and Siddharaatri. These are not nine separate goddesses. They represent the nine phases of the goddess' life. The nine nights of Navratri are a celebration of the Goddess in her entirety.

The Goddess is shakti, who brings meaning to Shiva, who disembodied pure consciousness. The first stage is Shailaputri, where Shakti is the goddess of the mountains. She is born of the mountains and she decides to marry the mountain hermit, Shiva. He, however, does not want to marry. He withdraws into his mountain cave, stubbornly refusing to be with her.
