“In the material world there are three principal deities called the trimurti (literally “three deities”). They correspond to God’s functions of creation, sustenance and destruction..
Brahma – the creator (in charge of raja-guna – the quality of passion). Brahma, the creator (or secondary creator, since he is born of Vishnu, the original creator). Direct worship of Brahma is rare, and in India there is only one major temple dedicated to him in Pushkar, Rajasthan. Some consider him to be worshiped indirectly through the chanting of the Gayatri mantra, since Gayatri is one of his consorts.
Vishnu – the maintainer in charge of sattva-guna – the quality of goodness). Vishnu, all-pervading yet also a person. He is most often worshiped in his forms as Krishna and Rama.
Shiva – the destroyer (in charge of tama-guna – the quality of ignorance). Shiva, with his carrier, Nandi the bull. Shiva is in charge of universal destruction, though he also has a role in creation. He represents the male principle within this world, while his female counterpart, Shakti, is his consort and the personification of material energy (Mother Nature).
God also exists beyond this world, as an impersonal force and/or as the Supreme Person. Most commonly that transcendent Supreme is identified with Vishnu, or one of his forms (such as Krishna, Rama, or Narayana).”
