From "Sickness is a defense against the truth", Lesson 136:

"No one can heal unless he understands what purpose sickness seems to serve. For then he understands as well its purpose has no meaning. Being causeless and without a meaningful intent of any kind, it cannot be at all. When this is seen, healing is automatic. It dispels this meaningless illusion by the same approach that carries all of them to truth, and merely leaves them there to disappear."

...

Here Jesus tells us simply that if we can clearly recognize a sickness for what it IS - an illusion, it will disappear automatically.

When we look at sickness we think it has a variety of causes. None of them are true. We also think it has a valuable purpose. The purpose is supposedly to defend our ego identity against truth. That's because we're mistaken about the truth and think that it will destroy us, so we "naturally" defend against it. Defense (denial) manifests reasons to believe that illusions are more real than God.

It is because we have a multitude of beliefs that tell us that sickness is real, that we have the sickness at all. It is sustained by those beliefs and created by them. It seems the sickness has no purpose and is a victimization, but really it does have a secret purpose. Its purpose was to block reality by demonstrating that illusions are real. Therefore we 'manifest' illusions that seem real, to try to prove that this is true. Manifesting illusions and making them real invents sickness.

We need to become willing to see instead that the purpose of sickness was to block the truth, not to make something true. It's purpose wasn't to affirm reality, it was to lend reality to something that is unreal. It's purpose wasn't to confirm how real the body is, but to deny how real the truth is. And finally we need to become able and willing to RECOGNIZE that sickness is an illusion, NOT a reality.

This is the defining principle. Sickness is the illusion that illusions are real. It is a denial of the truth - an attempt to hide the truth from awareness. This denial of truth causes sickness because it is your attempt to make God sick and dead. Your attempt to destroy God destroys you. Your belief that God (reality) is sick, produces sickness in your reality.

Your challenge in undoing sickness is to shift your sense of reality away from the sickness and place it on the real truth - God. If the sickness is true and real, God cannot be. And because your sickness is a choice to believe illusions are more real than reality, they are choices to believe that God is not real. They therefore block God, which is the giver of Life, and blocking life manifests as sickness (and death).

To undo sickness you must be willing to admit and recognize that sickness is not REAL, it is an illusion. It can't be real because of the ways in which God is real. God has to be more real than the sickness otherwise you will keep the sickness and continue to believe in its reality. Your belief in its reality is what puts it into your experience, because you are mis-creating.

You need to un-believe that the sickness is real in all its respects, in every way. There is nothing about sickness that can be "true" for you. Otherwise you will value it and keep it. When you can see that it LITERALLY is NOTHING, i.e. its an illusion that isn't real at all, you will cause it to disappear, because you will cease to GIVE it reality.

That's a miracle, an acknowledgement of God's truth and its equal meaningfulness to everyone.

"Who but yourself evaluates a threat, decides escape is necessary, and sets up a series of defenses to reduce the threat that has been judged as real? All this cannot be done unconsciously. But afterwards, your plan requires that you must forget you made it, so it seems to be external to your own intent; a happening beyond your state of mind, an outcome with a real effect on you, instead of one effected by yourself.

It is this quick forgetting of the part you play in making your "reality" that makes defenses seem to be beyond your own control."

- ACIM - sickness is a defense against the truth... Here Jesus describes how we create sickness.

We evaluate that the truth is a threat (to our ego truth), we decide we need to defend against it, so we create a sickness by making it real and doing it to ourselves, yet making it look like we didn't choose it. Jesus goes on to say...

"But what you have forgot can be remembered".

He also says:

"Defenses must make facts unrecognizable. They aim at doing this, and it is this they do."

and

"And yet you have forgotten that they stand but for your own decision of what should be real, to take the place of what is real."

i.e. sickness is an attempt to obscure the truth and make it unrecognizable by associating truth with something illusory. Sickness is illusory, so regarding it as truth obscures what the truth really is.

and ie... you use sickness to convert reality to untruth and illusions to reality.

We need to then remember we did this and uncover what the truth really is, to bring about healing.

At each stage from separation through sin, guilt, fear, punishment and death, there is always some amount of projection of the cause of the problem.

When we believe in separation, i.e. sin, sin actually makes the separation unconscious, and then we are unaware of what caused sin. That which has no cause is considered to be a cause in its own right and not an effect. We will then go searching for the cause somewhere external, other than accepting that we caused it.

So we'll claim, I am sinful because God says I'm sinful, instead of that its because we chose to believe in separation.

Then at the next stage, feeling guilty, we won't just say I'm guilty because I sinned, we'll project the cause of the guilt outward and find an external cause for it. I'm guilty because someone else says so, or because society finds me guilty. Always someone else deciding that the guilt is true. And once again the guilt renders awareness of sin unconscious, so you go looking for reasons that caused the guilt.

This carries on down to fear, whereby even though guilt causes fear, fear makes guilt unconscious, and then you go looking for a projected cause for the fear. You start to claim that you are afraid "because of" all the external things or future things which are making you afraid. But none of these things are the cause of fear, your guilt is.

Then when punishment is happening, instead of admitting that you are punishing yourself, you'll be claiming that you are punished because someone or something else is punishing you. You'll look to all these reasons and causes why you are punished, other than that fear causes punishment.

And on it goes to death. Death is someone else's fault, happens by someone else's hand, is entirely out of your control, is not chosen by you at all etc. Punishment causes death but here you're claiming that death is caused by everything other than yourself.

Projection happens at all levels, because every level is an attempt to disown the level before it, and thus disown responsibility for choosing it. As soon as there is separation there is a cascade of irresponsibility and projection. It doesn't just happen once you get to guilt. It happens at every stage of separation all the way through to death.

These projections, these stories about who or what caused or justified the guilt or sin or fear etc, are defenses protecting the defenses. Guilt defends against sin, and the story that someone else found you guilty or you're guilty because of what you did to someone, is a defense that protects guilt from being undone. These fictions and stories have to be dismantled in order to look squarely at the problem, and then you can dismantle the problem itself.

The story about what caused the fear or the guilt or the sin is a cover-up story. Underneath it is your own belief that you are sinful guilty and afraid. Then these believes also are a cover-up story. Fear defends guilt, guilt defends sin, sin defends separation. Collapse these one at a time and you'll end up at the Atonement.

Denial can be used two ways.

1) Deny God's truth and replace it with lies.

2) Deny lies and replace it with God's truth.

One defends the ego and makes God unreal. The other defends God and makes the ego unreal.

Denial of God has progressed very far and is responsible for everything that happens in this world.

Denial of ego is the only way to resurrect and return to safety.

Sometimes, denial is combined with level confusion. When this happens, you use denial incorrectly in the name of thinking that it's making you more spiritual, but instead it's increasing separation.

Denial of the body for example could go one of two ways. You could deny that it is real, which is correct, if done as a recognition that it is unreal and not as an attack on it seeming to be real.

Or, you could be believing the body is real and attempt to PRETEND it is not there, by using denial to attack it to try to make it go away. This will separate you from it and produce sickness, instead of transcending it.

In other words, denial needs to be used honestly and with clarity. If you are "in denial" about how you are using denial, that can be a problem.

Proper use of denial will entail a clear RECOGNITION of what something IS, without avoiding it or pretending to make it into something it is NOT.

Clear perception of what the ego is, what the body is, what illusions are, is all that is needed in order to "deny the ego". MISTAKEN perception will lead to the improper use of denial, because it means you see the ego as real instead of an illusion, and will then use denial to fight with it to try to make it go away.

Your whole mind is supposed to be everywhere.

The mind inside your body seems to be your conscious mind. The mind outside your body seems to be your unconscious mind.

While what is within your body seems to be different and separate from what is outside your body, you will see yourself as being the limits of your conscious self. Parts of you which are unconscious will be seen as outside of you.

Guilt which you put into your unconscious, so that your conscious mind can pretend to be innocent, will come up as seeming "events" in the outer world which come to teach you lessons. You will see them as attacks on your identity, at least at first, depending on your willingness to use them differently.

When what is within you is the same as what is outside of you, and when there is no further need for a separation to keep the two apart, the body will have no purpose and will disappear.

When what is within you is seen as also being within others, whereby what is in both of you is the same Christ mind, the same Self, your whole mind will be experienced as everywhere. That's because, like God, you are omnipresent.

The body was made only to create a sense of separation in the mind, a split between what hides within it and what hides outside of it. Its only purpose was to maintain an illusion of division so strong that it suggests the limits of your conscious self is the confines of the body.

You built a wall around the conscious self which, through a condensing of that idea, formed the illusion of bodies. Bodies are a barrier between what has been retained - the little innocent self - versus what has been rejected - the larger body of unconscious guilt which is disassociated from and appears to comprise "other people", i.e. "not self".

What is happening outside of the body is just a drama being orchestrated and run by the unconscious mind. Your unconscious mind. Events which happen in it represent the content of your own mind coming up into awareness to be reconsidered for forgiveness.

Forgiveness must entail a repair of the inner joining with the outer, of the separate embodied self rejoining with and beyond the embodied selves of others. What is in you is in them. What you are is what they are. You are one.

Joining of minds, which is miraculous, causes the body to be healed, because the body temporarily disappears. Its shift into invisibility, in light of the truth of oneness, heals it of its use as a device for separation.

Attempting to anchor self more heavily into the body and to tie the self to the body, simply makes the body more real and reinforces the separation between yourself and yourself. Such is the purpose of sickness which defends against unity by reinforcing separation, i.e. reinforcing the reality of the body as a wall that comes between you and your brother.

Your brother IS yourself. Those "others", those "not me"'s outside of you, ARE you. They are parts of the split mind of the sonship. You are to be reunited with them and share with them and join with them. This overlooks the body and it becomes meaningless and non-existent. It must disappear as inner and outer, self and not-self, become One.

In oneness there can be no separations.

You are everywhere. You are the whole sonship. You are the One Omnipresent Son of God.

When minds are separated, there is a gap between you and others. You become isolated. This prevents your mind from extending to and joining with other minds. It prevents you from recognizing your oneness with your brother, and so disrupts the holy relationship, induces separation, fosters specialness, and in turn increases body identification. You become anchored to the body and this increased fixation on the body causes it to become sick. It is under attack by beliefs in not sharing, selfishness and defensiveness.

"Perceiving the body AS A SEPARATE ENTITY cannot but foster illness"

"Learning must lead beyond the body to the re-establishment of the power of the mind IN it. This can be accomplished only if the mind EXTENDS to other minds, and does not ARREST ITSELF in its extension. The arrest of the mind's extension is the cause of all illness, because ONLY EXTENSION IS THE MIND'S FUNCTION. Block this, and you have blocked health because you have BLOCKED THE MIND'S JOY."

"Sickness is a defense against the truth"

"All forms of sickness even unto death are physical expressions of the fear of awakening."

Sickness arises, physically, as a result of the "fear of awakening" to the joined nature you share with your brother. It defends against the truth that you and your brother are one.

Therefore, by resuming extension of the mind through the body, to connect with and join to the minds of your brothers, recognizing your oneness with them, your sense of self expands back out past the body to be inclusive of others, the gap between you closes, the separation is erased, there is nothing to split your mind away from your brother's mind, and thus unity results. This unity erases all forms of separation and sickness. The gap, the "wound", is closed up.

"Healing is when two minds recognize their oneness and become glad."

"Miracles unite you with your brother."

The inevitable result of this is that the body is no longer the focus of identity, the mind is not contracting itself into the body, the body is not being attacked by the idea of isolation and separation, love is flowing through it again rather than visions of hell, and in turn the BODY is now healed as an effect of the joining of minds.

"The mind makes this decision as it makes every decision responsible for the condition of the body."

"The mind being sane heals the body."

All physical sickness results from and symbolizes the psychological sickness of contraction (fear) away from your brothers and the attempted severing of oneness with them. The restoration of that oneness is miraculous and forces the body to symbolize wholeness, healing, health, innocence, harmlessness, unity and freedom from attack. The body is induced into health as a natural byproduct of healed minds joining as one.

The body is a part of the equation. The body has not STATE of its own, it is ONLY a symbol, and not an end in itself, and it can only symbolize what the mind wants it to represent. It can either represent attack (sickness) as a result of separation of minds, or it can represent eternal life (wholeness, health) as a result of joined minds. Its condition is entirely an effect of the mind.

"The must be stronger than the body. Every miracle demonstrates this."

Where the mind is separating from others, it WILL induce physical sickness as a result of the fear of awakening to oneness, and as a defense against the truth of that oneness. When the mind is joining with others in love it WILL induce physical healing as a result of the overcoming of the fear of awakening and the disregarding of a NEED for a defense against the truth of your oneness with your brother.

Holy relationships heal the mind AND the body.

Special relationships cause sickness and death.

Holy Spirit's suggestion to take the next step in a healing, was to "cancel".

This means that you cancel, as in undo, your belief that an illusion is a reality. Whatever has been asserted by the ego as true or real, you cancel it. You confirm it is false and delete it from your mind.

So if someone seems to be sick, initially you probably believe that the sickness is real in various ways. You've seen it, heard about the symptoms, know the story, believe in the body, think it's actually happening, give it value, attribute it to various fake causes, etc. All of that needs to be collapsed because it is not God's truth.

So to cancel it, you first need to forgive, i.e. undo the delusions. You need to come to recognize that all of it is an illusion, NOT a reality. There is NOT a real sickness. The person is NOT a victim. The symptoms are NOT real. It is NOT really happening. The story is NOT the proof of how it happened. The explanation for it is NOT the real cause.

Cancel out all those false beliefs. Just reverse them. If they seem true, and if it's not God's truth, it is FALSE. This undoes all of the belief in the reality of the problem in your mind so that you're not SUSTAINING the sickness. Believing the sickness is real, at all, empowers it, fuels it, feeds it, keeps it, protects it, desires it, and chooses it.

So negate, cancel, undo, collapse, disappear, dissolve, make vanish, all of everything about 'it'. Get every single belief about the sickness being real out of yourself and out of your life. Get rid of all beliefs in sickness in yourself and others, let there be no permission for sickness to stay, reject all suggestions by everyone that sickness is real or true or permanent or justified, and do not believe in it.

Cancel the lies in whatever way that seems to be needed to get your mind to a place where you find yourself starting to state the core truths... like, there isn't even a sickness there, the sickness does not exist, there is no sickness, IT IS ALREADY GONE.

As you approach the truth, you are empowering yourself, by undoing those illusions. And you may (should) start to experience a building up of POWER in you. That's the Holy Spirit. Because you're aligning yourself with God's truth, you should start to feel His flow of 'electricity'. Your words are becoming more powerful, they are starting to contain Spirit, and you're expressing a higher vibration of love.

This is kind of like a prayer that ascends up to the truth of the Atonement: there is no real sin, nothing has happened, the sickness cannot exist because God did not create it. Or even, recognizing the sickness was a defense against the Atonement, there is no real NEED for the sickness, therefore the need for it was the problem that caused it, the need is unfounded, therefore the symptoms are unnecessary defenses. Illusions recognized as illusions must disappear.

As you hook yourself up to the truth, plugging your mind into God on one end, out of the other end you can utter miraculous healing words - commands of what MUST be, given God's truth. Dispel illusions, replace them with a higher order, something more symbolic of divine health. Speak LIFE into people. Stop them from constantly reinforcing, repeating, reiterating and compounding the reality of their problems. Someone needs to stop the madness and step in and make a statement of THE REAL TRUTH.

Later, you will then find that because you undid your own illusions about the sickness being real, you will not need to make much effort to defend against ego assertions that the healing didn't work etc... those thoughts mostly will not arise, and if they do you won't believe them. Because you already got done undoing the belief in those truths. This puts you on a much firmer footing for being convinced that, believing, that the healing has been accomplished by God and that the person MUST be healed.

Cancelling the delusions about sickness being real automatically cancels out the foundation for doubt, and doubt defends against miracles.

You'll defend something to the death if you think it's true. Your effort to be "right" about it is a combination of something that you believe is true combined with a sense of certainty. The power of conviction is not wrong, it is just misplaced onto something false. It's okay to acknowledge that your mind is powerful, it's just that it is 'mis-creating'.

If you are believing something is true which is actually false, and you are really adamant about it, it's going to take some 'undoing' to reverse this sense of conviction. You've probably built up a lot of "story" that explains, justified, rationalizes and establishes "why" this is true.

The more evidence you have gathered and the more you've "proven" it to yourself and talked yourself and others into it, the more volume of material is going to need to be undone. Those who are really extremely convinced of a lie are heavily "conditioned" by all of this psychological support, which may have come from culture or where you live or the kinds of people around you or your upbringing or experiences you had etc.

You'll need to look at what, in your belief system, 'supports' this truth. Look at all the scaffolding you've erected around it, all the supporting ideas and background information, the opinions of others, sources of authority that you believe in that support this truth, experiences you had which led you to be even more convinced this is true, affirmations that you make about its righteousness, ways you spin stories about it which back it up and regurgitate and reinforce it, how you defend it against other truth which seems to not be in accord with it, etc. All of these things add "weight" to this sense of it being real and valuable and correct.

It's not a problem to be correct. It's okay to be correct when you ARE correct. It's okay to be correct about Holy Spirit's truth which IS correct, and a correction of all else. But when you are correct about something that is an error or mistake or faulty conclusion or something based on dishonesty, it's going to present problems for you. You don't REALLY want to be right about how you need to suffer and die, for the sake of some "truth" that the ego has convinced you of, do you?

So as you pull apart your thought system you'll need to realize you've got all this support built up that defends this belief/truth and that all of that needs to be examined with Holy Spirit's light. It needs to be seen from a vantage point of a greater truth, otherwise you cannot recognize the falseness of it. You need to get outside of it and look in from a wider perspective.

For example, let's say you believe that you're in mortal danger because some body part seems to be failing and all the doctors said it's seriously bad and all your family members are showering you with sympathy and all you coworkers are retelling their own stories of woe and you've got yourself all worked up and terrified. Well, now this means that not only do you believe in sickness and so on but you also believe what your family and neighbors and coworkers are all telling you is the truth as well. And maybe you also "taught yourself" that all the doctors are well-trained and totally know what they're talking about, and that you don't dare question their authority. And maybe you yourself have justified to yourself why you need to be sick because it proves how guilty you are about something. All of these attitudes and opinions support keeping the problem real and true for you. You must be willing to question whether ANY of these supports are true.

What if absolutely everyone involved is telling you a lie, to show you what YOU believe that's a lie, and that you need to change your mind about what YOU think is true, so that they will stop telling you you're sure to die? Where is the empowerment and strength in listening to the voice for death? Where is the empowerment in not taking back responsibility for choosing to believe something that is grossly mistaken? You have to dismantle all of the lies that support the main lie in order for the main lie to be recognized as holding no ground. That it has no support. That it can't be justified. That it doesn't have any proof. And thus that you can't believe it. While you think lies are believable, you are stuck. The ego is literally unbelievable.

Forgetting for a moment the bigger picture context, which the ego always ignores, it can seem like this world makes sense.

The body seems to be able to see the world. Becoming sick seems to be something unwanted and an attack on us. The body seems to have senses of the environment and tells us what's there. The world seems real and outside of us.

But when you reintroduce the big-picture context of what happened before this world as made, it puts everything into a completely different perspective. It give you something to contrast again, to compare, is this true, or is it an illusion?

Before this world, you had vision, the ability to see in the light. There were no obstacles. When you made the world and the body, you created a kind of bubble, populated it with objects, painted the interior walls to shut out sight of God, and then fixated on the forms.

You made a body which was designed specifically to not see God, to focus only on form, to obsess over appearances and to be completely distracted by images seeming real. You made this world and the body to BURY YOUR HEAD IN THE SAND and NOT SEE. The whole purpose of the world is to DENY GOD.

The body was given so-called sensory organs, allegedly permitting you to see and sense the world. It was given eyes to be able to seeming have sight.

But all of this is completely inside out. And the reason and purpose of it is completely backwards.

The body's sight is made to make you BLIND. It is made to PREVENT VISION, so that you will be fixated on appearances, illusions, distractions, so that you DO NOT see. The more that you gain sight of form and bodies, the more blind you become. You SEEM to be seeing "more", but you are seeing LESS.

Similarly, it seems as though sickness is something we don't want and is attacking us against our will. We seem to "not want it". But the Course tells us that in the big picture, we put sickness in place on purpose to DEFEND ourselves against life, We actually think we are defending our SELF because we have identified with a fake ego self, and that self seems vulnerable (because it is an illusion) and needs defenses. So we defend the body in order to try to SAVE OUR LIFE from the attack of truth, which attacks the body and MAKES IT SICK. So now, in the big picture context, sickness is self-attack and a WANTED attempt to die, in the name of preserving your life!

We came into the world not to experience something real, but to get away from reality. We gave our body sensory abilities so as to NOT to sense what exists, but to confuse and block the ability to sense. We created eyesight to SUBSTITUTE for being able to see. The body can't see shit.

In this world, vision is blindness, sickness is self defense, life is death, death is life, what seems it will save you destroys you, defenses are attacks, everything is backwards and inside out and upside down. Nothing is as it appears. Even "nature" is unnatural. Everything about the ego's laws are unnatural. What is "supernatural" is actually natural. Miracles are natural. When they are not happening, something has gone wrong. They are supposed to be happening ALL THE TIME.

To be free of this must entail the undoing and letting go of, dissolving of, disappearing of, all of these illusory forms and things that we MADE UP solely for the PURPOSE of avoiding God. We can repurpose them temporarily and learn from them and use them for awakening, but they are only useful teaching devices for as long as we NEED to be taught, or rather to unlearn. Then we will let them go. Who would want to keep a body which sees only an inversion of reality, blocks vision and defends against God? It is unnatural. It is not needed.
