Vishnu, they say, is just one of a powerful threesome - the highest lords of the universe. However, though Brahma created the universe and Shiva can destroy it, it is up to the great god Vishnu to keep all creatures within well and happy.
Goddess Durga is the fierce form of Devi who, as Shakti, is considered the personification of Universal energy. According to the Devi Bhagavata, the universe is but her manifestation.
