Hinduism is one of the world's oldest religions, with over 1 billion followers. It is based on the Vedas, a collection of sacred texts, and teaches that there is one supreme being (Brahman) that can be realized through various paths. Hindus believe that all living beings contain a divine spark (atman) and follow dharma, or righteousness, through a cycle of rebirth and karma to achieve moksha, or liberation from samsara. The religion is characterized by diversity, flexibility, and tolerance of other faiths.
