Still working with the multidimensional reality/simultaneous time framework with reincarnation of a sort involved. Basically I see souls slitting as parts of them are "reincarnated" and live different lives. An "Earth" soul is just one that is focus here for a time. Lives/experiences can be chosen on other worlds, dimensions etc.
The material below I copied from something I had written at another time. I feel it may have some relevance, but does get off into my views on reincarnation and souls from that perspective.
The conventional view of time looks at reality as being 3D with changes occurring along a linear 4D timeline. With the advent of theoretical physics viewing reality as being multidimensional, time changes to being more of being a location with our physically focused consciousness changing perspectives in a linear/sequential manner.
The concept of reincarnation is usually based upon the commonly accepted view of time as being linear. The past is done and gone, the future exists only in our imagination and the present moment point is the only thing that has any reality. In this framework a series of lives are lived sequentially, one after another. Karma enters in where in your next life you seek to correct errors made in your past life. The goal is seeking a level of perfection which no longer requires enduring more physical lives and you are then free to exist in the spiritual realm. One question I have is what happens to the personalities of past lives? Do they just fade away becoming background part of future lives? Would this mean that the only one that means anything is the one that is the last incarnation? I must admit I am not too clear on how this is supposed to work.
Adjusting the framework from a linear time one to a multidimensional/simultaneous time one alters this idea in many ways. Past and future lives are happening NOW, only located in a different place temporally. This is similar, in our familiar physical 3D frame, to NYC and LA both existing NOW, but in different physical locations. Our consciousness is composed of different parts that deal with reality in different ways. Our waking physically focused consciousness deals with the day to day external reality that is our physical survival and life's experiences. This requires time being experienced as linear/sequential. Our body consciousness deals with the autonomic systems that maintain our physical form and health of our bodies. Then there is the "subconscious" that is focused on the non-physical, spiritual or psychic side of reality. Your non-physical astral body is a part of this. Time here is more of a spacious present with freedom to move about and even be in multiple locations simultaneously.
Each reincarnational personality is a unique soul and never loses its individuality. Let us begin explaining how this works starting with your death. Upon dying your consciousness is no longer physically focused as your waking consciousness is. What you initially experience is for the most part dependent upon what you believe will happen. The beginning of your afterlife is similar to when you are born in the physical world. Everything is new to you and you have to learn the rules of how things work. There are those “on the other side” who assist you in learning the ropes. Basically your thoughts and desires create the reality that you experience. Now, back to reincarnation, if you desire to experience and learn more from living physical lives you are able to do so. You also have the option to learn things while in the non-physical.
For those that choose to experience additional physical lives there are many options. You get to choose the time and circumstances of your birth. Timewise, you may choose a life in the past, present or future as all of time does exist at once. You choose your parents, as they also choose to have you. In choosing a life you are aware of all the possibilities that lie latent in this choice. Usually multiple lives in different times are chosen. All of these exist simultaneously, only located in different times. You more or less provide the psychic seed for the child to be born and the physical parents supply the physical sperm and egg. Usually the new consciousness enters the embryo around four months, but can be as late as the time of birth.
While each new identity you initiate is as unique as you are there is a gestalt of the psyche through which they are connected to each other through you. Essentially you act as an Oversoul, sometimes referred to as a guardian angel, which can make suggestions on some decisions making and offer guidance on a subconscious level. Similarly, your physical parents do the same thing on a physical waking consciousness level.
Still, it is up to the free will of each individual to make the final decisions in their own life. Subconsciously and in dreams you may learn from the experiences taking place in other of these reincarnational lives. This knowledge may assist you in current life situations or may uncover some “hidden” talents developed in another time. While this ended up being a bit long, I do feel it gives a good starting overview of reincarnation in a multidimensional/simultaneous time context.
Upon re-reading this I would like to clarify and/or add a couple things.
1. In each life it is not just a one timeline deal. Branching occurs that allows multiple options when choices are made. There will be parallel timelines following a core probability path. Even then, we are looking at probability clouds of minor variations for each. An example would be when you remember a past event. Each time you “remember” it you recall a slightly different version. Each version of “you” that is following another core probability timeline is a unique individual too. You see them as a probable you and they see you the same way. There is interaction between all.
2. You and the other reincarnational lives you may become aware of now are creations of an oversoul experiencing more lives focused in the physical. As I tried to cover earlier, when you die you will be in the same position as an oversoul to initiate new lives of YOUR choosing. There is a hierarchy of levels in which various levels share in the experiences. Communication is possible and asking for help from your higher selves may be accomplished.
3. What I have written is mainly focused on an Earth centered experience. This is not the only possibility. Other planets, other races, other dimensions etc. are all possible. All that is possible IS. Most of this is something we can’t even imagine. We are only at the beginning of a very long road that is an adventure that we construct.
