Hinduism is one of the oldest religions originating in India over 1500 BCE. It is a diverse set of traditions that believes in reincarnation and working to achieve moksha or liberation from the cycle of rebirth. Hindus worship many gods like Brahma, Vishnu, Shiva and see them as aspects of the single divine Brahman. They follow dharma or righteous living and believe one's karma or accumulated actions affect their situation in future lives. Key practices include yoga, following gurus, and pilgrimages to holy sites like the Ganges river. The caste system and festivals like Diwali are also important parts of Hindu traditions.
