Who makes the choice of conditions for a new incarnation?

How does the incarnation happen? In many places, over time, even centuries, it has been assumed that the disembodied individual had the faculty of being able to choose whether to incarnate in one place or another.
Beyond that - obviously impossible, because then everyone would be rich, beautiful and intelligent! - it is obvious that it is not possible that it is Akasic (conscience, ed), or the disembodied entity to choose its own incarnation.
If so, how could it be possible to structure Reality, as complex as it is?
You should realize that everyone would try to incarnate in the best possible way, everyone would try to avoid suffering, maybe there would be a frenzy because everyone would like to incarnate in one body instead of another!
Obviously this does not happen and there is something particular that sorts the disembodied entities - when it is time for incarnation - and causes there to be a certain order in coming to face incarnation on the physical plane.
Over time, I liked to reduce this factor that orders the incarnation to that element that we have decided to place at the center of our particular way of carrying the Teaching - I repeat: in our particular way of carrying the Teaching - that is "The vibration".
You know that everything that constitutes Reality is actually constituted by what?
From the vibration; which means that the individual's Akasic body itself, with its needs, its misunderstandings - but above all his needs, which are those that push the new incarnation - could theoretically be represented by the encoding of the vibration that characterizes him.
Explaining better: over the course of various lives the individual accumulates experience, thus accumulates "feel"; this feeling is inscribed inside the Akasic body as a vibration; this means that the vibrations of the Akasic body are transformed and change as the feeling widens and is completed for the individual.
The Akasic body, however, is not structured only by understandings, it is also structured by misunderstandings; how are these misunderstandings identified within the Akasic body? They are identifiable, in turn, as different vibrations.
So there are the vibrations of what one has understood and the vibrations of what the Akasic body has not yet understood.
When there is the drive to incarnation, or when the Akasic body has now received all the accumulated data in return, has put them all in their place, has inscribed all the right vibrations within it, here is the drive to return. on the physical plane to verify what is to be changed, and eventually understand other things.
What is it that guides this hypothetical journey (because what we are giving are only mental representations) of the Akasic body towards the physical world?
What drives it is the kind of vibrations that support it: the understandings and misunderstandings that the Akasic body has, have vibrations that somehow point towards the physical plane.
How is it then that the incarnation takes place? The incarnation takes place when, within the physical plane, there is a nucleus of vibration which in some way can be linked to those which are the typical vibrations of that Akasic body; therefore there is no "conscious choice" on the part of the akasic body, but there is a kind of being attracted (in the vibrations of the akasic body) to that situation within that family, within that new individual who is to be born , which, by affinity of vibration - in particular for what concerns the vibrations in need of understanding - vibrate in unison with him and therefore attract him, suck him towards physical matter.
It will thus happen that the individual will unite with this developing matter within the physical plane and the individual will see the light (the physical light, of course; not the other). Scifo
