Durga is a Goddess and is an eternal mother of all human beings and all other creatures on earth. She was called Durga because she killed an asur or giant named Durgam. During the month of October, Mother Durga is worshipped for nine days continuously with splendor and great fervour. She is worshipped in her nine different aspects namely, Shailputri, Brahamcharini, Chandraghanta, Kooshmanda, Skandmata, Katyayini, Kalratri, Mahagauri and Sidhdhidatri. Durga Puja is a Hindu festival, though Durga Puja is prevalent in all over India, Nepal, Sri Lanka and in other parts of the world where Hindus live, this festival is celebrated with great aplomb in West Bengal and in places where Bengla speaking persons reside. To celebrate it, people curve out a beautiful statue or idol of Mother Durga and install it at a fixed place with beautiful decoration all around her, sitting arrangements are made for the people thronging the place, devotional songs in praise of Mother are sung and Mother is worshipped with beating of drums and rhythmic dance, the whole spectacle is very enchanting and soul-stirring. On the tenth day, the idol of Mother is taken ceremoniously in a vehicle and it is immersed into the river nearby with full devotion. Another name of Mother Durga is Shakti ( power ) who is consort of Lord Shiva who is Lord of the World Himself. Shakti is deemed as the apparent aspect of Lord Himself and in a way a cause of whole creation while the other aspect of Lord is dormant and the most mysterious one and beyond the grasp of human mind, only ones who are blessed with a great insight or grace of God Himself can have a glimpse of that aspect of Lord Shiva, the One and the Only whom the whole world irrespective of religions worship. This dormant aspect of God is said to be without attributes but the other aspect is always active and can be called as the real cause of life force of all beings. So when we worship Mother Durga in her nine forms, we invoke the cause of whole creation, a very mysterious and subtle aspect of Lord Himself. Durga Puja is thus a worship of Lord Himself. People alien to Hinduism may mistake the worship of Mother Goddess for worship of Statue or Idol but in fact it is not that way. Hindus worship the Lord Himself that is why, a symbol like an idol or Statue is ultimately dissolved into the eternity. So when Hindus worship God as Mother, it means that we revere that aspect of the God who creates, energizes and cause destruction of the world.
