Hinduism views the entire universe as God's and everything in the universe as God. They believe that each person is divine and the purpose of life is to seek and realize the divinity within all of us. It believes in total non-exclusive and accepts all other faiths and religious paths.
They 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 beliefs of Hinduism is “atman,” or the belief in soul. This philosophy says that living creatures have a soul, and they're all part of the supreme soul.
The Rig Veda is the oldest known book in the world. This is because this IS the oldest religion known to man, the everlasting and 3rd largest in the world.
