Hinduism is the world's oldest religion, according to many scholars, with roots and customs dating back more than 4,000 years.Hindus believe in the doctrines of samsara (the continuous cycle of life, death, and reincarnation) and karma (the universal law of cause and effect). One of the key thoughts of Hinduism is “atman,” or the belief in soul. This philosophy holds that living creatures have a soul, and they're all part of the supreme soul.
