Hinduism is one of the oldest religions in the world originating from the Vedas. It believes in one supreme God that can take many forms. Some key beliefs include dharma, samsara, karma, and moksha. While it is often seen as polytheistic, Hindus believe the many deities are manifestations of Brahman, the singular ultimate reality. The triumvirate of Brahma, Vishnu, and Shiva represent different aspects of God. Popular forms include Ganesha, Krishna, Lakshmi, and Saraswati.
