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.
If one nation becomes more efficient than another nation at producing a specific product, the more efficient nation is said to have a comparative advantage. This economic idea was first developed by David Ricardo.
