This section from "the healing of the dream", Chapter 27, is radical, awesome and mind bending all at once.
It speaks of how forgiveness, which you apply, should not simply forgive, but must also heal YOUR BODY, in order to demonstrate to your brother that HE is forgiven also. That unless forgiveness does this, forgiveness is not COMPLETE.
Some may think this is ridiculous, incorrect, or meaningless. Why show your brother a healed imaginary body? Why bother to heal the body at all? Yet Jesus is VERY clear, that until our forgiveness produces healing of BOTH YOU AND YOUR BROTHER, through a miracle, it is not done.
He goes even further to say that PROVING through DEMONSTRATION that your body is HEALTHY, by healing it along with your mind, speaks far more powerfully to your brother’s sinlessness than anything else you could do.
This is why Jesus also says elsewhere, "the mind AND BODY need atonement", "the mind must be stronger than the body, every miracle DEMONSTRATES this", and "A guiltless mind cannot suffer. Being sane, it HEALS THE BODY."
Open your mind. Take a deep breathe. This speaks to the real power of miracle working even at the PHYSICAL level.
"Forgiveness is not real unless it brings a healing to your brother and yourself. You must attest his sins have no effect on you to demonstrate they are 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 that cannot be undone and overlooked entirely. In their undoing lies the proof that they are merely errors. Let yourself be healed that you may be forgiving, offering salvation to your brother and yourself.
5 A broken body shows the mind has not been healed. A miracle of healing proves that separation is without effect. What you would prove to him you will believe. The power of witness comes from your belief. And everything you say or do or think but testifies to what you teach to him. 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 of his innocence. It is this testimony that can speak with power greater than a thousand tongues. For here is his forgiveness proved to him.
6 A miracle can offer nothing less to him than it has given unto you. So does your healing 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. 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. The ancient calling of the Father to His Son, and of the Son unto His Own, will yet be the last trumpet that the world will ever hear. Brother, there is no death. And this you learn when you but wish to show your brother that you had no hurt of him. He thinks your blood is on his hands, and so he stands condemned. Yet it is given you to show him, by your healing, that his guilt is but the fabric of a senseless dream.
7 How just are miracles! For they bestow an equal gift of full deliverance from guilt upon your brother and yourself. Your healing saves him pain as well as you, and you are healed because you wished him well. This is the law the miracle obeys; that healing sees no specialness at all. It does not come from pity but from love. And love would prove all suffering is but a vain imagining, a foolish wish with no effects. Your health is a result of your desire to see your brother with no blood upon his hands, nor guilt upon his heart made heavy with the proof of sin. And what you wish is given you to see."
