Giving and receiving must occur simultaneously.
This means that in order to receive love and healing, you must give love and healing.
Which in turn means, that the only way for you to be healed, is to extend healing to others.
Which therefore means, that your willingness to heal your brothers heals you.
"I will be healed as I let him teach me to heal (self and others)."
This is a key point because when you focus on "your" healing or "your body" that in fact is falling short of extension. As you fixate on "what is wrong with me", you are failing to forgive and overlook it.
What's needed is the re-establishing of your function of healing, which happens through extending PAST the body to others.
If you seem to be sick, it is because you have not loved yourself AND other enough. As ACIM says, those who are sick do not love themselves. But to love yourself you have to love PAST yourself because love has to be shared.
"If to love oneself is to HEAL oneself, those who are sick do NOT love themselves."
"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."
As you become willing to give, you are praying to receive. You can only receive by becoming part of the giving. When prayer is asking to get and not give, it is asking for sacrifice. And when prayer is asking to give and not receive, it is asking for sacrifice.
You have to be included in the prayer that asks to receive, because you must be part of the functioning of giving. The "flow" through you as a conduit for God only works when you are willing to be part of the transmission of that which you want to affirm is in you and through you.
When the mind's extension is arrested ie held back, through the body, and begins to fixate on your body or another body, it is not fully joining minds. It is falling short. Love is being held back. There is resistance and fear. This induces illness.
Once illness is induced and you are deceived, the temptation is to continue believing that since you are sick, you need to address the sickness. But focusing on the sickness does not look past it. It is the sharing, extending, and looking past your body that re-establishes the proper functioning of the mind. Once mind is extending/forgiving past the body, it is shining a light, and that light heals your body indirectly.
So the trick to this is that if you need healing it is because you are not healing. To heal, you need to heal others. By being of service, you receive support. By extending love you receive love. As ACIM says "Love goes out because of what it is, but you are needed that it can begin." If you block it is cannot extend. You must participate in the giving, to open up your vessel so that love can flow through.
Jesus tells us, "you are healed because you wished him well." As you wish your brother well it heals you. If you attack your brother you will attack yourself. If you try to accuse your brother of sin, you will be accused. If you prepare a list of effects and suffering that you wish your brother to endure, you can be sure that you will be the one who experiences them. You cannot be healed alone, nor can you escape the effects of your thinking.
It's important to realize then that not only is healing not "just you getting healed alone", but also sickness is not about "you being sick alone". Sickness is an attempt to come between brothers and to attack BOTH you and your brother, driving a separation between you, using the body as a separation device and attempting to increase the rift.
Making the body "more real" by focusing in it, increases its symptoms, in an effort to convey that it strongly comes between you. Your sick body acts like a solid brick wall blocking you off from others, attacking them keeping you imprisoned. Similarly healing cannot entail merely the repair of "your self", it HAS to entail the REJOINING and SHARING with your brother, to undo the rift that caused the sickness in the first place.
No-one is sick in isolation. In contagion do the sick seek to kill others. Sick bodies are accusers. If "you" seem to go into sickness it is because you are attempting to accuse your brother of your sins. Which means you believe you are sinful AND that your brother is sinful. And this means you see yourself in a sickened state AND your brother in a sickened state. It may well be that you seem to be the only one suffering but it is because psychologically you have separated yourself off from others.
No-one heals in isolation. Isolation must end for there to be healing. To be healed yourself, you cannot hold grievances against others, you cannot project sin, and you cannot find your brother to be guilty. By the Golden Rule, what applies to you applies to them. For you to experience healing, mentally and or physically, you have to be willing to see your brother healed. "Forgiveness is not real unless it has brought a healing to your brother AND yourself."
The temptation is to think you are the only one sick. The belief in "I am alone" produces sickness because it ends sharing. Therefore the opposite, "We are joined", produces health because it acknowledges that in their natural healthy state, minds are joined as one. And you can only ever join in LOVE.
It's almost as though you should "ignore" (overlook) what seems to be "exclusive sickness" and focus more on extending love to others, which shines past the sickness and erases it. If your sickness is a barrier to sharing, sharing is the remedy. The sickness was an attempt to disable yourself so that you could NOT share. The solution is to share and extend love in defiance of the barriers you've erected so that they are shone away.
Sickness then is an attempt to isolate, to cut yourself off, to be exclusive and special, to be different, to not share, to hide and to be in the dark. Healing must then be a matter of joining, reunion, equality, sharing, coming into the light, opening up to extension, and allowing your brother back in. This means receiving all of the sonship again, developing holy relationships, and moving past the illusions of separation.
When Christ Mind is shining through a body in wholeness and love, the body is shone past, making it illuminated and healed and transparent, eventually to disappear entirely. Bodies are interference, originally made as devices for separation. To use them with the Holy Spirit is to UNDO them. "The body cannot remain without illusions."
"Christ is within a frame of holiness, whose ONLY purpose is that He may be made manifest to those who know Him not; that He may call to them to come to Him, and see Him where they THOUGHT their bodies were. Then will their bodies melt away, that they may frame His holiness in them."
"The body needs NO healing. But the mind that thinks it IS a body is sick indeed! And it is here that Christ sets forth the remedy. His PURPOSE folds the body in His light, and fills it with the holiness that shines from HIM. And nothing that the body says or does but makes HIM manifest. To those who know Him not it carries Him, in gentleness and love, to heal their minds. Such is the mission that your brother has for YOU. And such it MUST be that YOUR mission is for HIM."
