These three forms or faces of the Trimurti represent God's roles of creation, preservation and destruction, which are associated with Brahma (the source or creator), Vishnu (the preserver or indwelling-life), and Shiva (the destroyer and transformer) respectively. Some Hindus use these cosmological functions of the three gods to create an acronym for "GOD"; that is Generator (Brahma), Operator (Vishnu) and Destroyer (Shiva).
