In ACIM Jesus says the ego made the body as a way to focus away from the mind and to make the mind seem to be 'private'. The body is like a wall around the mind which creates the illusion and perception that the mind does not communicate. In other words, the mind seems to be shut off from all other equally-separate minds, and there is no sharing on any level of awareness.
The result of this is that the body is now exalted as a means of communication, in which the ego wants bodies to become physically intimate to 'represent' communication happening. Even the spoken word is then considered communication, but really it is a complete substitute for real, direct communication, and typically is a communication failure.
True Communication isn't telepathy as such, the idea of telepathy means separate people with separate minds sending messages. The truth is that our minds are NOT separate, and the belief in a separation between minds is the cause of all sickness, all mental illness, and death. And this is why the body dies - because the mind has been kept from true communication and locked in a prison. Or to put it another way, the body HAS to die if the mind remains unaware of its true function, because the body IS the idea of death.
Jesus talks about how the ego will do anything it can to ignore the mind, and will even let the mind have activity and thoughts because it thinks of it as serving the body and allowing the body to tell the mind what to do. Then the body uses the mind only so that the body can get what it wants, such as property, clothing, sex, food, physical contact, etc. You can see this reflected in the scientific/medical model which says that the 'brain' is the cause of consciousness or is the 'source' of thinking, which is completely the opposite of the truth.
This heavy focus on the physical, as well as this reversal of who is in charge - i.e. that the body is in charge of the mind, is a "confusion of the levels", which Jesus also explains as the cause of all sickness. "All sickness comes from confusing the levels" ... and that miracles correct this 'order' and place the levels in their proper order - i.e., restoring the mind as CAUSE and the body as EFFECT.
The body did not exist at all until the ego made it as a way to enslave the mind, to make you unaware that you even have a mind, to shut out awareness, to cut you off from everyone else, to make you isolated and lonely, and to disempower you. This was the PURPOSE of the body. This is the body's entire reason for existing. It is not some lovely creature that God created and that we should bow down and worship. It is an ego device for separation and for splitting the One Shared Mind into many many small imprisoned minds.
I had an experience of God a few years ago and in this experience my mind became very expanded, and I became very very aware. I thought I was fully awake when I woke up in the morning but it was absolutely nothing in comparison to how awake and aware I was in this experience. I became quite close to leaving my body because I was becoming very aware of God and the attraction to Him was so strong, that I wanted to leave absolutely everything behind and go to Him. It was like a scared child running to their parent after some nightmarish thing just happened and finally realizing that they can run to safety.
However, this didn't last very long and my expanded awareness and unification of mind started to come back into my body. I was extremely ungrounded for some time and gradually my awareness collapsed back down and reinserted itself into my body. This took a few weeks. As it progressed, I felt and perceived that it was like undergoing some kind of brain damage - as though coming into the body was taking on a tremendous dumbing down, suppressing, 'disabling', stunting of my consciousness, such that I could only liken it to having some kind of terrible brain damage that was blocking out and shutting out the beautiful awareness I'd experienced.
Towards the end of this process of 'returning' to the ego, which was very upsetting because once you taste God you don't want to leave... my awareness gradually entered into my physical senses more fully and this was like putting on a dark costume where, once you get inside it enough, the door behind you closes, your sense of connection to God gets almost completely shut off, your awareness of anything bigger is totally shut down, and you are sort of 'locked in'. Then, it seems that the only thing you can be aware of is what the body's senses show you - there is information coming into the eyes, tastes, smells, sounds etc, but very little awareness, no connection, no expansion, no real communication, and no God.
It's sort of like some creepy thing like, entering "The Matrix", or getting plugged into a virtual reality suit where, once you go into it, all of real reality gets shut out and you can ONLY fixate on what the 'encounter-suit' shows you. This is because the body forces you to focus on form, on what's outside of you, and what's separate from you. It totally shuts out your connection to the whole and makes you feel like some kind of tiny little, strapped-in prisoner, who can barely move or perceive anything, with blinders on, forced to stare at a make-believe world and not allowed to look at any thing else. This was really upsetting to go through 're-entry' but it showed me clearly just how much the body blocks awareness and shuts down the mind.
We can ascend our awareness to a heavenly place, I mean, when I was having my experience I was still in my body, just about, but such an expanded state of being really urges for total release from the body, it's so expansive that the body cannot contain it. At some point, as I see it, when we really thoroughly wake up not just to the Higher Self (sonship) but also beyond to Christ and to Heaven, it would become extremely, extremely difficult to maintain a body at all, and more than likely the mind would have to completely leave bodies entirely and then only return in the form of a kind of apparition or temporary image, which the mind is not at all imprisoned by.
So you see, the body is not an idol. It is not God's greatest creation. It is not something to worship. it is not what people are. It's not what you are. It is a very heavy, very isolating, very imprisoning suit of armor, deliberately made as a device for blocking awareness and diminishing the mind. It is the manifestation of an attempt to be separate from God. It is an illusion of minds no longer being joined. And when minds become joined and the mind becomes miraculous, the body has to heal, up to a point, but then the mind will stop creating a body.
How can a mind that knows of absolute oneness have any use for the body at all? Yes Holy Spirit can use it for TRUE communication, which means the MIND communicated with other minds directly - or rather, "shares". But the body itself is nothing but a temporary tool in a temporary dream, which we do not NEED in order to exist and therefore is not an inherent part of life. When Jesus was done with His body he saw no further truth in it and it DISAPPEARED. But he remained, because He is immortal spirit. And so are you.
P.S. "virtual reality" devices are now a metaphor for this... you strap on an artificial body, all of your visual senses are completely imprisoned and shut out from perceiving the 'real room', you go inside a fantasy world that doesn't exist, and you see only what this artificial body wants you to see. Your mind and awareness of the room outside is completely shut off, and you are immersed in a dream that you think is real. All the while real characters go about their business in the same room knowing, from the outside, that you are asleep inside a fake body looking at a fake world. So it is with the human body. And the body will eventually have to be 'taken off' from the mind to allow awareness to be fully aware of what is real.
