What are the main beliefs of Hinduism?

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.
