Many people's hope for afterlife comes from the belief that the body is a shell or a container etc that house an invisible entity termed 'the soul'. The soul, so it is said, is the cause of our consciousness and sometimes it is equated to the consciousness itself. One difficulty that arises from this idea comes from the fact that we cannot exit our bodies at will. Why can't we simply leave our bodies behind once and for all and go to heaven and enjoy the bliss forever? This gives rise to the notion that our bodies somehow 'traps' the soul. Since our bodies are composed of charges of opposite signs etc, it is tempting to suppose that any such a system such as a computer can similarly trap the soul so that just like the way we can never exit our bodies, someone might, in future, invent a device that can hopelessly trap us forever inside say a machine, and possibly torturing us even forever! Thus the very hope of an afterlife is effectively turned on its own head!
The 'original sin' comes from the baseless belief that our consciousness is due to an unseen, entity that the supposedly understandable matter can somehow 'trap' it without itself being understandable, and hence 'there being no need' to carefully think of, and attempt to understand what we are believing in. I vehemingly reject this approach! We should try to understand 'the soul' as much as we do, 'the body'. We must try to explain how the body, or the soul, can achieve this fleat of 'getting trapped into each other' without them 'being on the same universe.
It comes as a surprise to many people to learn that if the soul is what we are, then it can, at least in principle, be studied scientifically! This being the case, we can also create theoretical models to 'explain' the soul, just like we do, to explain the forces of nature, such as gravity. To a careful physicist, or a philosopher, etc, the soul interacting with the body must come about like a 'fifth force' that has an effect in our bodies. This 'fifth force' can be discovered by carefully studying the brain and specifically noting how there is an effect that cannot be accounted for by known forces.
Since it seems that some people find it hard to understand this fact that 'soul' is discoverable by the usual scientific method, let me try to elucidate it more. Now, in a 'vacuum', we know how charged particles behave, in accordance with laws of electrodynamics. So for instance under a constant voltage, they will accelerate steadily. But if they encounter a 'soul' on its way, generaly they will alter their acceleration in such a way that a physicis will notice that either something is wrong with the laws of electrodynamics or there is some yet unknown 'fift force' that is at work on the particle. However the soul has just acted upon the charge in exactly the same manner it would have acted upon the charges in your brain so that it may eventually influence the body to act in a certain manner, e.g. raising your hand in what we term it as 'our conscious decision'. So it is clear that we cannot answer the question as to why the soul has never been detected by physicists by saying 'it is beyond understanding' or 'we feel it' or 'the mind is limited' or such jocker cards. These are false, absurd and misleading! We can and should understand 'soul' up to the point of explaining how it is consistent with known facts. To do that, we must make some model for 'soul'.
One explanation is that the disembodied 'soul' does not interact with charges. This bestows the soul with mechanisms of enabling and disabling its ability to interact with electromagnetism. This mechanism must be instantaneous. Upon exiting the body, the soul must be able to instantaneously switch off its electromagnetism. But this ability also automatically makes the soul incapable of being trapped by another machine, e.g. a computer. But since we can't use this ability to intentionally exit our bodies, there must be some rules followed by the soul that has no counterpart in the rules followed by the matter.

But we can see that this scenario is exactly the same as 'vacuum polarization', with the only difference being that we are using charges in place of magnets, and the 'vacuum' itself in the place of the tape. Since our bodies, and especially the brain activities are charges, our brain behaves exactly like the magnetic tape recorder. Since we move through space, the 'empty space' records every activity in our brains!!
But I can even go far more ahead and explain why the 'vacuum' is exactly like the magnetic tape using the equations of quantum electrodynamics!!

The activity crucial to generation of consciousness is just the charge polarization across the cell membranes in the neurones. But like you can see it in the diagram below, every charged particle creats a corresponding polarization in the 'vacuum' that effectively recreats a slightly bigger but invisible charger right next to the charged particle. In other words, every charged particle 'induces its own charge' into the 'vacuum'. This means that the entire pattern of charges is the cell membrane that generates your consciousness is exactly replicated in the vacuum! Furthermore it is done in such a way that there are ever more layers of 'charge bodies' that are created on top of each other, forming what looks like a giant onion! So if consciousness is due to pattern of charges a cross the cell membrane, like they insists, then the very same consciousness can be induced into the 'vacuum'.
It only remains to wonder what happens once the body is removed. But this one rings a bell! This is the exact way the magnetic tape recording works, albeit we use magnetic poles in place of charges. If you polarize the magnetic tape using the magnetized head, the polarization persists even after you remove the head, recording the info!
Also the whatever info in the 'polarized body', it will be very 'deem' to the awarenes, especially after the body is removed, much in the same way the polarized tape requires amplification. This explains why we dont experience our awareness in the 'empty space'. As long as there is the strong charge that is our seen body, it eclipses the faint charge in the vacuum just like the sun eclipses the stars in daytime. However, when we die, or when we sleep, things becomes different, and we might begin experiencing the more unseen body together with its own experiences, much like the way stars get revealed during the night.

But since the proponents of 'soul' are often stubborn in the 'immaterial' or 'not science' ideas, I will put it more bluntly and state that given our modern scientific understanding of 'empty space', we nolonger need any 'soul'! This is because we have a reason to believe that 'empty space' can possess consciousness and also can transmitt it from one brain to another. We don't need another unknown, so called 'immaterial' entity to explain reincarnation etc. Neither do we need to insist that our consciousness is not the result of the physical brain. This is because we now understand that there are invisible things in 'empty space' that are similar to the brain as far as 'taking consciousness' is concerned. So afterlife, reincarnation etc can still take place even if brain is what generates our consciousness.
So 'immaterial entities' are superfluous. If you insist that 'soul' must be 'immaterial', then I will tell you bluntly that we don't need such an entity!
This is more than analogy. In QM, the wavicles spreads throughout the whole space so that every particle is technically 'omnipresent', just like in holograms. The discrete particles manifest at a region where the waves pile up so that their amplitudes add up at a given region and then diminish rapidly with distance, forming the famous 'Gaussian bell'. This is exactly how holograms are made!
Your 'soul' then is spatially extended away from your body, just like the presence of earth is felt on moon via its gravity. In every region where you 'aura' is there, the experience is communicated throughout. While the seen body is alife, the information flowing to the body, which is communicated to every point in the 'aura', eclipses all the info flowing to those other portions. This creats the illusion that 'we are inside our bodies'. So 'the soul comming out of the body' is not literal. We are just realizing the soul's existence outside of the body as well. This also explains why meditation might reveal other unseen world. It 'deems' the seen world in some way.
