Hinduism is one of the oldest religions in the world originating from the Vedas. It is based on the concepts of dharma, samsara, karma, and moksha. While often seen as polytheistic, Hinduism views the deities as manifestations of the singular, supreme Brahman. Different gods represent different aspects of Brahman to suit various types of people. Key figures include Brahma, Vishnu, Shiva representing the Trimurti, Krishna as the eighth avatar of Vishnu, and goddesses Lakshmi and Saraswati.
