Monistic Tritheism
The Hindu Trinity of Brahma the creator, Vishnu the preserver and Shiva the destroyer has also been said to constitute a Tritheistic belief system. Like the Christian Trinity, these beings are understood to work ultimately in harmony with one another, but this Hindu trinity does not have doctrinal status as in trinitarian Christianity, but is posited as simply one of many ways in which the Divine order of the universe may be understood. Ultimately, however, the Universal Spirit, the Param-atman, the Brahman (not to be confused with brahmin, a social class / caste), or Bhagvan reigns supreme, as one divine entity, in Hindu theology.
