It is argued, further, that Reincarnation fits in with the known scientific principle of conservation of energy--that is, that no energy is ever created or is lost, but that all energy is but a form of the universal energy, which flows on from form to form, from manifestation to manifestation, ever the same, and yet manifesting in myriad forms--never born, never dying, but always moving on, and on, and on to new manifestations. Therefore it is thought that it is reasonable to suppose that the soul follows the same law of re-embodiment, rising higher and higher, throughout time, until finally it re-enters the Universal Spirit from which it emerged, and in which it will continue to exist, as it existed before it emerged for the cycle of manifestation. It is also argued that Reincarnation brings Life within the Law of Cause and Effect, just as is everything else in the universe. The law of re-birth, according to the causes generated during past lives, would bring the existence of the soul within and in harmony with natural laws, instead of without and contrary to them. It is further argued that the feeling of "original sin" of which so many people assert a consciousness, may be explained better by the theory of Reincarnation than by any theological doctrine. The orthodox doctrine is that "original sin" was something inherited from Adam by reason of our forefather's transgression, but this jars upon the thought of today, as well it might, for what has the "soul" to do with Adam--it did not descend from him, or from aught else but the Source of Being--there is no line of descent for souls, though there may be for bodies. What has Adam to do with your soul, if it came fresh from the mint of the Maker, pure and unsullied--how could his sin taint your new soul? Theology here asserts either arrant nonsense, or else grave injustice. But if for "Adam" we substitute our past existences and the thoughts and deeds thereof, we may understand that feeling of conscious recognition of past wrong-doing and remorse, which so many testify to, though they be reasonably free from the same in the present life. The butterfly dimly remembers its worm state, and although it now soars, it feels the slime of the mud in which it once crawled.
