Goddess Durga is the mother of the universe and believed to be the power behind the work of creation, preservation, and destruction of the world. Since time immemorial she has been worshipped as the supreme power of the Supreme.
The word "Durga" in Sanskrit means a fort, or a place which is difficult to overrun. Another meaning of "Durga" is "Durgatinashini," which literally translates into "the one who eliminates sufferings." Thus, Hindus believe that goddess Durga protects her devotees from the evils of the world and at the same time removes their miseries.
