This is in great accordance with the picture that I pieced together, based on personal insights, astrological research, Hermetic writings, and quantum physics. Not that it would answer all my questions, but this is, in outline, what I concluded so far:
After physical death, the subtle body ascends through what was called the "planetary spheres" in the Hermetic/neo-Platonic cosmology of the ancients - we might speak of subtle planes or other-dimensional levels of reality today. During its "ascent", the subtle body gradually sheds its various layers, which correspond with the individual's intellect, emotions etc. For each of these layers is made of a different kind of subtle matter, and each is eventually left on its corresponding sphere or plane: The intellectual faculties on the plane of Mercury, the emotions on the planes of Venus and Mars etc.
What remains is the soul essence or monad, which is the individual's innermost identity beyond thinking and feeling. It will naturally gravitate toward realms beyond the Solar System, ultimately joining the Infinity of space and time. The Judeo-Christian tradition reflects this by stating that the soul returns to God.
Yet that spark of the Divine in most cases once again descends through the various planes, gradually dressing itself with new subtle body and, eventually, with a physical body. They will reflect the earlier experiences of this entity. Its make up is represented by its natal chart. There are indeed no two exactly identical individuals regarding their thinking, feeling, and physicality, as there are no two exactly identical natal charts. However, there will be considerable parallels between its earlier and the later "versions". Often, there will also be differences due to evolutionary integrations that have occurred during the previous incarnation.
By my experiences with channeling this would be correct in the concept, except the fact of not being an automatic process.
Please let me explain.
The spheres of the planets of astrology are multi-fractal.
The astrologic influences are actually all derivated from aether fluxes in our own planet, and are imprinted on the person's aether body - a semi-physical body which makes the connection between the physical body and the emotional body (which would be the sphere of Luna in your conceptual analysis).
(side note: Interestingly, this body start to scatter immediately after death of a person, and it's energy is needed for emotional beyings to affect the physical plane. So, the idea of "scattering" of the "soul", on my view, is actually based on the fact of the scattering of the aether body.)
However, astrology does go beyond this and gives us a conceptual analysis of the spheres above our own.
Above the sphere of deep emotion (Luna or the Astral Plane) we have the sphere of thought (mercury or the Concrete Mental Plane) then the sphere of sexuality and fluxes of instinc, or freudian libido, without form (Venus or the Abstract Mental Plane), then the sphere of Destiny, Dharma or Karma (Sun or the Causal Plane), then the sphere of strenght or impulse of movement (Mars or the Adamic Plane) then the sphere of royalty and supremacy (Jupiter or the Celestial Plane).
Above the Solar Sphere regular human beings do not have Individuality anymore. We are already part of a Group-Consciousness.
Above the Jupiterian Sphere there is no "humanity" anymore. The Saturnian Sphere is already on the verge of the Limits of Existance for what we call "humanity".
There are, however, classes of entities which can go beyond those levels. For instance, by reaching enlightment it is possible to leave humanity behind and achieve individuality on the level of the Martian sphere.
That said, death of the physical boddy do not allow for imediate return to the un-individual states of existance.
Most people just exist on the emotional plane after death. Plus, differently from here, destroying the emotional body (or soul) completely is impossible.
It is possible to mutilate it, to drain it of energy, to make it mutated and semi-destroyed, but there is a basic level of immortality to it.
In fact, it is to avoid the deterioration of the emotional body to a state of great suffering that most submit themselves to reincarnation on a new physical body, even if most in the situation of death see this as "dying" in the soul world, whislt the actual death of the emotional body is seen as "ascention".
That because, to reach the "gift" of death in the emotional plane it's necessary to reach a certain level of spiritual enlightnment.
Not to become buddha or something, but at least on the level of a Bodissatva, since it is necessary to be able to remain in the emotional plane indefinitely, cristalizing the existence of the emotional body there - meaning to be out of Samsara.
So, yes, when death comes we can rise out of the physical body and "shed" the "skin" of the multiple subtle bodies we have.
The first "skin" is the emotional body, or astral body, or soul, which must be first purified to the highest possible level and then abbandoned and finally scatter.
The difference is we actually need to seek for it and work towards it - while in the physical plane we seek to keep life.
Another question, if past life regression is possible, why not future life progression? Is there a ring pass not, wherein we can guide the mind to the past but not the future, if time collapses in the subtler fields underneath reality, it seems like both should be possible, in that we can access all lives (sensory input and subsequent reactions) through the memory of Nature, so that life experience is not limited to an ego or HG/daimon.
I know at least a couple people who have experienced future progression.
However, the thing with future is that it isn't written in stone.
There are multiple futures, and we, that is, our consciousness, will experience only one of them at a time (at least i don't know of anyone experiencing more than one at the same time).
So, it is possible to do a progression, see a perfectly possible future, and then just don't live it.
I have had, once or twice in my life, a few flases of future insight. I also know of people who had them.
Now, the interesting thing is, in one of them I was having a discussion with my mother. I used a certain argument, it became sour.
When the thing started to happen in real life, i, remembering the argument which turned the discussion sour, decided to change it.
And it did change. The discussion didn't became sour.
My brother-in-law also had future insight on a possible driving accident. He saw himself driving, and a man would pass the red light and crash into him.
As it commonly happens, he saw the vision, forgot it, and in the day the thing was going to happen, he remembered it.
So, he hit the brakes on time, and the guy didn't crash on him.
Now, the opposit has also happened with me.
I have also seen a scene of future, and done the thing i saw myself doing. What happened?
The scene progressed as it was perceived by me in the first place.
On another note, i did have some passing stuff, like perceiving just myself sat somewhere with a certain emotion or mental state. Not seeing how i got on this condition, i couldn't do a thing to avoid it.
So, the simple knowledge of future is enought to change it. The greater the knowledge, the more you can choose what to keep and what to change - but the smaller it is, the less power you have.
By having a progression you take a risk.
You may change the future without desiring it. You may keep it because you don't know how to change it, or if it is even possible to change it, or you may just get lucky and see enough to allow yourself to control what will happen.
Regardless, it's an interesting practice.
