Goddess Durga is worshipped in different forms. SHE is a form of "Shakti". The evolution of Shri Maha Saraswati, Shri Maha Laxmi and Shri Mahakali (the 3 main forms of "Shakti") took place from Shri Brahma, Shri Vishnu and Shri Mahesh respectively.

Each of these 3 deities gave rise to 3 more forms and hence in all, these 9 forms together are known as Nav-Durga.
