Χίντου, or Hinduism, is one of the world's oldest religions, originating in the Indian subcontinent. It encompasses a variety of beliefs, practices, and rituals, with no single founder or central religious authority. Key concepts include dharma (duty), karma (action and its consequences), and moksha (liberation from the cycle of rebirth). The religion is characterized by a rich tapestry of deities, texts, and traditions. Major scriptures include the Vedas, Upanishads, and the Bhagavad Gita. Worship can take place in temples or at home, and festivals like Diwali and Holi are celebrated with great enthusiasm by followers around the world.
