The goal is true self-realization. Self-realization is to know that you are a soul, a part of God, yet also the Whole. Perhaps no one has a very good image at all of his or her soul - the whole self. And they have no idea of what proportion their personality is in relationship to their soul. As an example, a characteristic of your personality is one percent of all of your personality characteristics put together, and all of your personality characteristics make up your personality, and your personality is only about five percent of your soul, then we are blinding ourselves to 95 percent of the rest of our soul in order to reincarnate.
Reincarnation is an opportunity to evolve through many personalities.
The definition of reincarnation is that your personality is who you are in your current lifetime, and that it can be reincarnated as an entirely different personality with the characteristics of the previous personality and previous personalities including even characteristics of another soul altogether. That is, characteristics of your present personality may be the reincarnation of other characteristics of personalities from your previous lifetimes as well as characteristics from personalities from other souls. If a person dies and goes totally homogenous back into the Light it is reasonably improbable that there will be another reincarnation. It is improbable. However, it is more usual for people to die and go partially back into the Light while remaining partially in the realm of the earth plane.
