The formation, beginning or initiation of an entity, thought, idea, plan or design. As spirit, we have always existed, but as a separate conscious individual we start this expression when mating conception takes place. From the time that the cells have coalesced and formed their union, the tiny particle of spirit has naturally attached itself and begins its expression in the world of matter. Personality, on the other hand, is formed at birth when the neurons of the brain are formed (see Astrology).
