----TL;DR: Changing your perception OF a sick body, isn't enough to change what you are projecting. You are projecting your body and the symptoms.----
"Projection makes perception. The world that you see is what you have put there to see; nothing more and nothing less and so it is important to you. The world that you perceive is the witness to your state of mind, the outward picture of your inward condition. As you think so do you perceive."
Recognize that projection COMES FIRST, then perception happens SECOND.
"The world you see" (perceive) "is what you have put there to see" (what you projected first).
"The world you perceive" (second) "is witness to your state of mind" - your perception "witnesses", perceives, and reflects back to you, your state of mind, because your state of mind PROJECTED what it is that you are now PERCEIVING.
These are two different processes. The act of having a certain state of mind, which you then project FROM, puts stuff "out there", which you THEN perceive as a secondary process.
Even the body itself is a projection. "The body is the idea of sin made flesh and projected outwards". The body then PERCEIVES, AFTER having been projected.
Jesus talks about how this is a circular logic for us, a trap, whereby we believe what we want to see, we project it because we believe in it, we "make it appear" (manifest it), then we "perceive" ie let the body tell us what it is we projected.
Perception then, is distinct from projection. It is a secondary act. Without projecting, there would be nothing TO perceive.
So here's what you need to realize about perceptions of sickness.
The mind, in whatever state it is in, has beliefs in it, thoughts, which then project. These projections MANIFEST the body and many other forms and objects. The mind for example projects the body ITSELF.
If the mind has a belief in separation, it will project a body which shows up with signs and symptoms of sickness, because it is a PICTURE of your inward condition, and your inward condition is one of "I am under attack". So the body SHOWS it. it is a WITNESS ie corresponds to your state of mind. This is why "a broken body is proof the mind has not been healed." The body literally only shows up as the mind's manifestational projection. It's an image being projected by the mind.
Jesus speaks to this in his "special notes to helen"....
"My body disappeared because I had no illusion about it.. It merely became what it always was. ... The body disappears, and no longer hides what lies beyond... To roll the stone away is to see beyond the tomb, beyond death, and to understand the body's nothingness.
I did assume a human form with human attributes afterwards, to speak to those who were to prove the body's worthlessness to the world. This has been much misunderstood.
I came to tell them that death is an illusion, and THE MIND THAT MADE THE BODY CAN MAKE ANOTHER SINCE FORM ITSELF IS AN ILLUSION. They did not understand."
So here we can see, the MIND, MAKES the body. Your mind is projecting your body, and everything about it, right now. However it is showing up, witnesses to your mental content and your belief system. If it is showing up as sick, it is therefore directly correlated, it is PROOF, that your mind is not healed.
This also means, that when the mind IS healed, or close to, and it is still projecting a body, it MUST project a body which appears without signs or symptoms of sickness. This is because the body COMES FROM the mind, mind is its source, and a healthy mind WILL ONLY project a healthy-appearing body image.
Now. There is a problem here in how many people are interpreting the correction of perception.
Remember perception happens to look upon WHAT YOU PROJECTED, after you projected it. The body's eyes receive little photons of light to tell it, oh look, there's a body there. That's part of perception. The illusion that the very thing YOU PROJECTED, is now telling you what IT IS, completely forgetting that you put it there in the first place.
So now perception, is ONCE REMOVED from the direct expression or projection of the mind. Perception therefore is a secondary experience.
So now, let's say that you have projected a body with a broken leg. The broken leg was not caused by anything in the world. It was ONLY projected from the mind. The mind did not project a broken leg ONTO the body. The mind directly projected ONLY an image of a body with a broken leg. The body does not EXIST as a separate object, or a "thing", or something as an end in itself. If you do not project it, nothing shows up! If you do not project it, there is no body!
So now, that you projected an image of a body with a broken leg, you now will perceive. Perception can be in a state of correctness/clarity or in a state of false perception/distortion. Since your MIND has a belief in sickness in it, and has made a sick-appearing body image materialize, it also now believes sickness is real. Perception is now going to take place, and that same mind which PROJECTED the "sick body", is also going to see that same belief in sickness IN the body that was projected.
This means perception is now going to show you a hallucination of "sickness is real", "something is wrong", "sin and guilt" etc, as though it is *IN* the body. It is not in the body, it's in the mind. Thus the idea of sickness, which made the body to begin with, is now SECONDARILY projected ON TOP OF the body that you projected.
Then you will have various ego reactions to what you are misperceiving, and will start to seek a resolution. But your planned strategy here isn't typically anything to do with fixing your PROJECTION, it's always to do with fixing your PERCEPTION. And that means, something very obvious is about to happen.
If all you do, is fix your perception OF what you projected, you might be able to seem to "be at peace" with what is showing up. You might seem to become less upset or resistant or less fighting with, your broken leg. You'll tell yourself, if your perception OF the body is healed, you will be TOTALLY DONE. But this leaves you with a problem, and a state of denial.
Fact is, even if your so-called "perception" is perceiving your broken leg as "lovely and wonderful", oh how lovely that death looks.... your leg is STILL BROKEN. And that's a problem. Because now you are demonstrating that you can be hurt, you are attacking the entire world by claiming that something OTHER THAN YOU put the break there, you are holding this broken leg up for everyone to see to make them guilty and accuse them of sin, and you are attempting to demonstrate that God's Son can be killed.
It also means that since ALL sickness manifests as a DEFENSE against the truth, in the mind, which then projects a "defending body", which shows up as attacked, you CANNOT accept full and total peace while still maintaining that defense. It is impossible. The defense has to go, which means the belief in separation has to go, which MUST produce a projected body which shows up as HEALED.
Nothing happens to the body that was sick that you projected previously. It does not exist. You just RE-PROJECT A NEW ONE, every moment. Sickness in the body can only show up if the mind is defending against truth, and sickness can only show up in the body if the mind has GUILT. "Sickness is but another form of guilt". Therefore, if the mind does not have guilt and defenses, the body WILL ONLY show up as healed, as PROOF, that the mind is healed. The mind will PROJECT a healed-appearing body to testify to ITS inner condition.
So while that broken leg persists, you are in denial. You may be owning up to the fact that you have some control over your PERCEPTION. But you are not admitting that you have the power to PROJECT what you are even looking at.
This is a fundamental difference and there is a pretty big divide in the ACIM community based around this one distinction. Many people believe all they need to do is fix their perception OF the world, or what's showing up, and then they are done. In this belief system, it becomes justified that you can still have sickness show up and have a "healthy mind", that you can still DIE and be innocent, you can welcome death, you can keep your sickness and be totally happy, etc.
Yes, to a degree, as a preparatory step, you can come to be "relatively peaceful" about these things through changing your perception. What you are INDIRECTLY doing there, is that it's not actually your perception that you're fixing, is the content of your mind that PROJECTS the body in the first place. Attempting to change your perception is a second-hand roundabout way of trying to address the content in your mind, which is "showing you" a belief in sin and sickness "in" the broken leg. But at some point.... you're going to hit a wall.
The wall will simply be, that in order for you to really thoroughly change your perception so that you do not believe in sickness, and have no sickness in your mind, you're going to have to also ADMIT, that your mind is projecting the FORM OF SICKNESS *AS* the body, in the first place, regardless of your perception OF it.
So many people are onto this "change my mind about the world" kick, which changes perception OF the world. But they do not realize, at some point, if you are not going to perceive sickness, your mind has to be emptied of all belief in sickness, AND THIS MUST result in the PROJECTION changing. It has to. The mind can't retain some small amount of belief in separation and have *perception* be a state of peace.
If that broken leg is still showing up, but you are relatively "ok with it", you are IN DENIAL. That broken leg is NOT SUPPOSED TO BE SHOWING UP AT ALL. A sick body is PROOF the mind HAS NOT been healed.
There is this second camp of ACIM folk then who see this, and acknowledge, that the mind projects the body. Jesus Himself said it in that quote above. The mind that projects the body can make another. And if the mind can project the ENTIRE BODY, then IT is 100% responsible for making the body show up with ANY sign of sickness or death. This is how no-one can die without his own consent! If your mind does not put it there, it cannot be.
So if you just stop at.... I'm going to just be okay with this sickness, I'm going to perceive this sickness differently, I'm going to perceive this BODY differently, I'm going to look at this body in a more loving way etc.... that's a step TOWARDS healing the mind's content. But if that body is still showing up as BROKEN, you are NOT DONE.
This is where there comes to be a lot of denial, because not only is it often difficult to see that you projected the sickness AS the body (it can happen really fast and then go unconscious), there is also a lot of FEAR about this idea that your mind is THAT POWERFUL, that it can not only make sickness and death happen to you BY your will, but that the mind can also reverse that. Yet Jesus teaches:
"You made sickness and death and therefore can abolish both." ABOLISH means, to TOTALLY REMOVE. That means, the reversal of ALL forms and signs and symptoms of sickness in the body AND mind, and EVEN DEATH. It Literally means, the ability to reverse death, to raise the dead, and to completely restore life. It is the ability to REWIND SIN and UNDO ALL OF THE CONSEQUENCES (effects) of your wrong decision.
Your mind is cause. Your body is your effect. The body is NOT CAUSED by the world in any way whatsoever. Ever. Your sickness is NOT PUT THERE by any cause outside of your mind, EVER. You are responsible for what you have chosen. And because you are, you can CHANGE YOUR MIND and it MUST CHANGE THE PROJECTION.
So yes it's one thing to work on changing your perception, but your perception has arisen from what you have projected. And that means, if you are GENUINELY undoing the sinful content in your mind, are taking full ownership of your power, are NOT believing that anything in the world has the power to affect you or your body, and are NOT attempting to demonstrate that the Son of God can be hurt and killed THROUGH the symbol of the body (the body can become a sign of immortality), then YOU WILL STOP PROJECTING SICKNESS AND DEATH.
You do not project it ONTO the body. You project it AS the body. No-one else put the body there. Your parents did not put the body there. Biology did not put the body there. Chemical reactions and physical interactions did not put the body there. The world, the dream, other people, did not put the body there. ONLY YOU DID.
So that means, if you're to go all the way with this.... this is where you get into MIRACLE WORKING. Because it means, you are willing to DEMONSTRATE, to live by example, that it is possible to reverse all sickness and death in yourself, AND IN OTHERS.
You first reverse it in yourself by accepting atonement. This allows you to receive miracles. Then you are able to express those miracles to and for others. If they are willing to accept it.
We are not supposed to be walking around with limbs hanging off and body parts failing and organs malfunctioning and eyesight going bad and developing a limp and a having cancers and diseases and various other forms of SIN.
Death is an attempt to demonstrate that the Son of God can be killed. Pain is an attempt to bind the son to the body to fixate him on and identify with being a real body. Sickness is an attempt to prove the Son can be hurt. Sickness is an attack on your brother. Sickness is the result of seeking outside of yourself, and demonstrates level confusion. None of this is God's will. It is a demonstration of the OPPOSITE OF GOD'S WILL for you.
No-one is supposed to be dying. Bodies are not supposed to be decaying and dying. There is NOT supposed to be 7 billion people planning their own death, who will very likely die in the next 100 years, putting 7 billion corpses in the ground, just because they did not want God's healing and love. That's their choice. It does not have to be yours.
If we are to demonstrate that we are immortal and invulnerable, we ARE supposed to demonstrate here, in the flesh, that the body cannot be hurt, BECAUSE, the body is ONLY coming from the mind, and therefore if you project a healthy body it will STAY HEALTHY at all times. And nothing can attack it. It is IMPOSSIBLE for it to be sick. NOR CAN IT DIE.
"Use it to bring the Word of God to those who have it not, and the body becomes holy. Because it is holy it cannot be sick, nor can it die. When its usefulness is done it is laid by, and that is all. The mind makes this decision, as IT MAKES ALL DECISIONS THAT ARE RESPONSIBLE FOR THE BODY'S CONDITION."
Later, when it's done being useful, it is simply DISAPPEARED. Just as Jesus did:
"My body disappeared because I had no illusion about it.. It merely became what it always was. And that is what 'rolling the stone away means.' The body disappears, and no longer hides what lies beyond... To roll the stone away is to see beyond the tomb, beyond death, and to understand the body's nothingness. "
It was not a matter of it disappearing from his perception OF it. The body ITSELF disappeared because HE STOPPED PROJECTING IT.
THIS is our natural inheritance, this ability to work miracles, to reverse all sickness and death, to not only correct perception but to CORRECT PROJECTION. To UNDO everything we have PROJECTED. AND that ultimately includes your body, everyone else's body, all sickness, all death, all forms of separation, all objects, all planets, and this entire ILLUSORY UNIVERSE which is a PROJECTION coming from the mind.
So don't stop at "I will just change how I see the world." "Seek not to change the world, seek to change your mind about the world. Perception is a RESULT (effect of projecting) and not a cause (the body that shows up is not alive!). "And that is why order of difficulty in miracles is meaningless." ie... change your MIND, your body and the world MUST CHANGE to reflect the content of your mind. Without exception.
There are people who wake up in this world. There are people who are awake in the dream. There are people who have purified perception to such an extent that they seem to be seeing the real world or something close to it. They recognize that they were contributing sin to what is here, projecting it "onto" the body and world. But what they usually do not realize is, THEY are projecting the body and the world. And therefore, typically, they age, and they die. And then they reincarnate and make another body. Why? Because they did not get to the level where they woke up FROM dreaming, and FROM perceiving.
To wake up FROM the dream, you have to get in touch with the fact that you are the DREAMER of it, the one who is PROJECTING IT, and you are the one who is PUTTING ALL OF ITS OBJECTS OUT THERE. This puts you in touch with miracle working because now you are able to enact VERTICAL PERCEPTION, cause and effect are now vertical not linear, and you recognize the power of YOUR MIND to manifest absolutely anything in this dream, or change it, at will. Because you will realize, you have been DOING THAT all along. Your body was coming from YOUR MIND, and your mind only.
To wake up from the dream requires the undoing of dreaming, which overrides ALL perception, deals with separation at ITS CAUSE, and therefore DISAPPEARS THE DREAM UNIVERSE. That means, the disappearance of the physical universe, including precious "planet earth", which was never anything but a mental projection. All that is then left, is God's creation, which is Heaven.
