"The sick are merciless to everyone, and in contagion do they seek to kill. Death seems an easy price, if they can say, "Behold me, brother, at your hand I die." For sickness is the witness to his guilt, and death would prove his errors MUST be sins."
You are one with your brother. What applies to you applies to him, per the Golden Rule. What is true of him is true of you. What you do to him you do to yourself.
Therefore, when you go into separation, you create a separation BETWEEN you and your brothers. You accuse yourself AND YOUR BROTHER of sin, simultaneously.
The result of doing so is that you arrest the extension of the mind, which INDUCES ILLNESS. The body thus becomes sick, as part of your effort to accuse yourself and your brother of being sinful.
This means that YOUR BODY, and its condition, are part of a COMMUNICATION that you are having with your brother. Whatever your body seems to say about you, it ALSO says about him. Sickness is not in isolation, it is a double-edged sword. It may seem only to state that YOU are sick, bit it ALSO states that HE is sick.
You cannot believe in your own sickness WITHOUT believing in your brother being sick. This is why your body becomes a two-sided weapon through which you are attacking yourself AND your brother. This is why sickness takes on forms of contagion, which represent the desire to kill your brother and yourself simultaneously.
Since your body is a "physical message" to him and yourself, which you believe, it is also your attempt to FORCE him to believe the same. Due to the golden rule, whatever you make true of the body, you are claiming is also true of him. Thus your body in is sickened state, actively condemns your brother and attempts to teach him he is not innocent. Thus it imprisons him.
More to the point, when your mind is reunited with your brother in joint union, and the gap of separation if healed away, the body in fact becomes a messenger of healing. It now symbolically communicates to BOTH of you that you AND your brother are innocent. In fact it now becomes a way to TEACH him that HE IS HEALED, and therefore prevent him from believing that he has sinned.
Through a demonstration of a physically HEALED body, there is no longer proof of sin, no longer tangible evidence of accusation, and now your brother is exonerated. This has a HEALING EFFECT on his mind and HE IS HEALED ALONG WITH YOU.
The body sends a MESSAGE to your brother, with a power greater than a thousand tongues, TEACHING HIM of his innocence OR his guilt, depending on what you are teaching yourself. When your mind is healed it WILL NOT teach sin, and will NOT make the body sick, and WILL heal your mind, and your body, and his mind, and his body.
"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 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."
The body is used to PROVE that you have forgiven your brother! Which is why "a broken body shows (proves) the mind HAS NOT been healed."
"The body can become a sign of life, a promise of redemption, and a breath of immortality to those grown sick of breathing in the fetid scent of death. Let it have healing as its PURPOSE. Then will ***it send forth the message it received, and by its health and loveliness proclaim the truth*** and value that it represents. Let it receive the power to represent an endless life, forever unattacked. And to your brother let its message be, "Behold me, brother, at your hand I live."
Your body must demonstrate "because you did not sin against me, my body is not attacked, and we must both therefore be innocent." And in order to accomplish this, MIRACLES ARE REQUIRED THAT HEAL THE BODY, so that the body CAN be FIXED AND HEALED, in order to allow it to teach ONLY innocence.
That means even if your brother attacks and damages your body, YOU RESURRECT IT, in order to PROVE TO HIM that you have forgiven him. When there is no sin, there are no effects of sin, and all sickness and death disappear.
