Brahma – the creator (in charge of raja-guna – the quality of passion).
Vishnu – the maintainer (in charge of sattva-guna – the quality of goodness).
Shiva – the destroyer (in charge of tama-guna – the quality of ignorance).
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 (see also Prakriti and Guna).
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).
