One of the cornerstone beliefs of many world religions such as Hinduism, Buddhism, Jainism, Sikhism, Taoism, Shintoism, and Zoroastrianism, is the idea of reincarnation.
From the Orphics, Pythagoreans, and Platonists to the Essenes, Pharisees, and Karaites; from Polynesian Kahunas and Brazillian Umbandas to the Jamaican Rastafarians and American Indians; the Gauls, the Druids, the Celts, the Gnostics, and even early Christians all believed in reincarnation.
Great minds like Plato, Socrates, Spinoza, Leibnitz, Voltaire, Hume, Schopenhauer, Goethe, Emerson, Whitman, Napoleon, Franklin, Tagore, and Ghandi all believed that our consciousness, our souls, survive bodily death and continue on.
