In this world, sin is an EVENT. In fact, it is anything that seems to HAPPEN. Any physical change, any transformation of materials, any movement, any action, anything bodies of any kind do, any chemical interactions of particles, it is sin.
"The world of bodies is the world of sin."
Sin is also insanity.
"Sin is insanity. It is the means by which the mind is driven mad, and seeks to let illusions take the place of truth. And being mad, it sees illusions where truth should be, and where it really is. Sin gave the body eyes, for what is there the sinless would behold?"
The whole world, all of spacetime, anything the body can see, is a model of sin and punishment for sin. "Everything the body sees is a form of error."
"And FROM this error does the world of sin and sacrifice arise. This world is an attempt to prove your innocence, while cherishing attack."
"The world you see is the delusional system of those made mad by guilt. Look carefully at this world, and you will realize that this is so. For this world is the symbol of punishment, and all the laws that seem to govern it are the laws of death."
The physical world, matter, is also referred to in the course as a granite block of sin. The illusion of physicality, rooted in the idea of PHYSICAL SIN. This is why sin requires a BODY, because only bodies can PHYSICALLY SIN.
"Sin is a block, set like a heavy gate, locked and without a key, across the road to peace. No-one who looks on it without the help of reason, would try to pass it. ****The body's eyes behold it as solid granite****, so thick it would be madness to attempt to pass it. Yet reason sees through it (x-ray christ vision) easily, BECAUSE it is an error."
"And ***they were made to look on error, and not see past it***. Theirs is indeed a strange perception, for they can see only illusions, unable to look beyond the granite block of sin, and stopping at the outside form of nothing. To this distorted form of vision, the outside of everything, the wall that stands between you and the truth, is wholly true."
So basically, the entire physical universe is formed on the idea of sin. Everything that seems to transpire is sin. Breathing, eating, sleeping, working, laughing, milking a cow, sucking a milkshake, it's all sin. Even just the appearance of an illusion or a physical world AT ALL is sin.
It's sin in that sin is the idea of "something happening" or "something existing which doesn't", or "the impossible seeming possible", that "affects" something else seemingly against its will. Like a collision of two forces. And this is fundamental to the laws of physics.
When one thing "hits" another, it is the idea of sin taking place, that there can be a conflict, a war, a collision of interests, in which one thing is impacted seeming from outside of its own will.
And when sin occurs on this level, in this realm of spacetime, physical matter seems to change, reacting with effects and consequences. Materials change, properties change, objects change their locations, atoms rearrange, forces and counter-forces interact, and the whole picture shifts and changes and suffers and dies.
If anything CAN be changed, it CANNOT be real, because nothing real can be threatened. So that means that any change that occurs in anything, is artificial evidence that SIN IS HAPPENING TO IT. It is an illusion of sin, and not reality, but in THIS world it appears to "really happen".
This is why in this world, when you attack something, and it produces a "change" in any way, the change now TESTIFIES that "sin has occurred." If something happens to something else, and it is modified, and now it is different, and it seems to DEMONSTRATE that it is different, and maintains its "new state" for anyone to point a finger at and say, "look there, SOMETHING HAPPENED TO IT" .... this changed state is a PROOF OF SIN.
It then does not matter how you frame it. If the PHYSICAL EVIDENCE is still there to look at, to point out, to touch and see and evaluate, then it PROVES that SIN DID TAKE PLACE. You can't have effects without causes. This is how the ego "locks in" the consequences of sin, and uses physical evidence to PROVE that sin has occurred. If you can measure it, it's a sin.
This means that if you are playing in the realm of illusions, of physicality, you are automatically dabbling in sin. Because the WHOLE WORLD is founded on the idea of sin.
"The body is the idea of sin made flesh"
So let's say that someone seems to attack your body and this produces a CHANGE in the body. Maybe some kind of wound is inflicted, some kind of damage. The body is bleeding and there is a hole. Well, this physical appearance PROVES beyond a shadow of a doubt to anyone looking at it and thinking it real, that SIN HAPPENED. It testifies to it. You can't deny if, if you think it's reality.
You cannot claim that sin did not happen IF THE RESULTS ARE STILL THERE. If I can point a finger at it and say, well, it doesn't matter WHAT you claim, the EVIDENCE is still there, the body IS STILL WOUNDED, then it STILL SHOWS that SIN HAPPENED. There is no getting around this. Changing your perception to recognize that "there is no sin" also isn't the same thing as REVERSING THE CONSEQUENCES.
"Thus does the ****miracle undo all things the world attests can never BE undone.**** And hopelessness ***and death MUST disappear*** before the ancient clarion call of life. This call has power FAR beyond the weak and miserable cry of death and guilt."
When attack is taking place, or more to the point, when a person REFUSES TO HEAL the effects of the sin, to reverse the physical symptoms of sickness, or to REMOVE the PROOF OF SIN from the body, then there is still ACCUSATION OF SIN HAPPENING. Because if the body is STILL damaged, the UNDENIABLE PROOF is still sitting right there staring you in the face. A damaged body is STILL testifying that NO MATTER what the state of mind is, or how forgiving you think you are, SIN STILL HAPPENED. I can look at it, I can see it, I can touch it, sin has NOT been undone. I can't claim to be holy while showing you PROOF THAT YOU SINNED!!
"For no-one in whom true forgiveness reigns CAN suffer. ***He holds not the proof of sin before his brother's eyes.*** And thus he MUST have overlooked it, and removed it from his own. Forgiveness CANNOT be for one, and not the other. Who forgives IS healed. And in his (mental AND physical) healing lies the PROOF that he has truly pardoned, and retains no trace of condemnation that he still would hold against himself or any living thing."
"Only the mind AND body need atonement." ---- AND THE BODY NEEDS ATONEMENT!!
Do you see here that Jesus is literally saying that you MUST heal the body of any signs of attack, otherwise it STILL PROVES that sin happened?
If you hold a "proof of sin" before your brother's eyes - the wounds, the scars, the fallout, the consequences, the broken limbs, whatever. If you hold it in front of them you are SHOWING HIM consequential, cause-effect PROOF, that because this EFFECT is here, A CAUSE MUST HAVE BEEN HERE ALSO. And that testifies in a way that cannot be denied that you HAVE NOT forgiven him or yourself.
This is why Jesus says that forgiveness is not complete, is not real, and has not been finished, IF the PROOF OF SIN has not been removed. That means, the PHYSICAL EVIDENCE HAS TO BE UNDONE. THE BODY HAS TO BE HEALED, otherwise you HAVE NOT forgiven him.
This vital paragraph tells you exactly that.
"***Forgiveness is not real UNLESS it brings a healing to your brother AND yourself.*** ***YOU must attest his sins had no effect on YOU, to demonstrate they were not real.*** How else COULD he be guiltless? And how COULD his innocence be justified UNLESS his sins have no effect to WARRANT guilt? Sins are beyond forgiveness just BECAUSE they would entail effects which CANNOT be undone and overlooked entirely. In their UNDOING lies the proof that they were merely errors. LET yourself be healed, that you may be forgiving, offering salvation to your brother AND yourself. A broken body shows the mind has NOT been healed. A miracle of healing proves that separation is WITHOUT effect."
To demonstrate his sins were NOT REAL, you must SHOW HIM that THE EFFECTS ARE GONE.
You can only attest his sins had NO EFFECT on you, or your body, by REMOVING THE EFFECTS. If you still have the effects to show him, you are not only still accusing him ("sick bodies remain accusers"), you also HAVE NOT finished forgiving. Because effects REQUIRE an ONGOING CAUSE, and if the effects remains, you are STILL ATTACKING HIM for it. This is what the course is saying. You must heal the body in order NOT to accuse your brother of sin.
Forgiveness HAS TO INCLUDE the UNDOING OF PHYSICAL PROOF OF SIN. If it does not bring a physical healing along with it, and if all the signs and effects of the DOING OF SIN are not COMPLETELY OBLITERATED, the mind HAS NOT been healed and it still harbors attack thoughts and a purpose for accusation.
"A damaged body shows the mind has not been healed."
So you cannot say you are DONE forgiving, if PHYSICAL SYMPTOMS still remain. You cannot say you are DONE forgiving, if the BODY is still sick. You cannot say that a healing has taken place, if the BODY and the ENVIRONMENT testify in ANY WAY, to the PRESENCE OF PROOF that "something happened."
It has to be that all of the proof vanishes. If I spill milk on the kitchen floor, and there is STILL milk on the kitchen floor, IT PROVES that I MUST have spilled the milk. I cannot deny that. So long as the milk is ON THE FLOOR, there remains proof. The EFFECTS IMPLY that there WAS A CAUSE. Because you cannot have effects WITHOUT a cause. If the effects remain, it PROVES that a CAUSE did happen. And causation is tied to sin.
"Nothing can have effects without a cause"
And in this world, cause is SIN. So if someone CAUSES your body to be wounded, they CAUSED a sin. And the effects are the wound. And until the WOUND IS GONE, the sin is still PROVEN, which ACCUSES your brother and damns him to hell. This imprisons his mind and curses him to death.
So Jesus does in fact ask that even in this world, even in bodies, even if it's an illusion, and even if it seems to be meaningless, that you HEAL THE BODY of all effects of attack, IN ORDER TO exonerate your brother and TEACH HIM of his innocence. WHILE you have a body.
If he attempted to attack your body, chopping off your arms, and then you return and your ARMS ARE RESTORED.... HE has no way in his mind to connect cause and effect, he sees that HE CANNOT HAVE SINNED, and that your HEALING PROVES HIS INNOCENCE. And thereby he now recognizes that the SYMBOLIC HEALTH of your body TESTIFIES to his innocence, and this PROOF OF INNOCENCE ... HEALS HIS MIND. Physical health EXONERATES your brother, just as sickness is an ACCUSATION OF SIN.
"For accusation is a bar to love, and damaged bodies ARE accusers." "Your body can be means to ***teach that it has never suffered pain because of him***. And in its healing can it offer him mute testimony to his innocence. It is THIS testimony that can speak ***with power greater than a thousand tongues.***
**********For here is his forgiveness PROVED to him. *********
A miracle can offer nothing LESS to him than it has given unto you. So does your healing (mind and body) show your mind is healed, and has forgiven ***what he did NOT do***. And so is HE convinced his innocence was never lost, *****and healed along with you.****"
This is using the physical body as a communication device FOR HEALING! Using it as a symbol of innocence. And using it to AFFECT YOUR BROTHER'S MIND. Your healing and your health IS your brother's healing and health. When you are healed, you are not healed alone, EVEN on the physical level.
This is what Jesus's physical resurrection was all about. "SHOW your brother you had no hurt of him."
