This is the title of ACIM lesson 125. The essence here is to realize that everything you give, you receive, because giving and receiving are one. Per the golden rule, whatever you "do to another", you literally and directly and personally do to yourself. Anything at all that comes out of you, goes back into you.
This is the law of God, and it is inescapable. But it seems to be very difficult to recognize this law is in effect. It seems possible that you do something to another and experience none of the consequences. That somehow there is a separation between what applies to the giver and the receiver.
The body in particular makes it seem possible to do something to another while escaping the effects. One body can seem to hurt another, and yet come away with no apparent harm. This violates the law of God and seems to suggest the golden rule does not apply. But the laws of God always apply.
If you were aware that anything you do is done to BOTH yourself and others, you would be very careful in choosing what to do. If when you poked another's body, you felt a poke of your own body, you would hesitate to poke them. If you attacked their body and immediately felt the hurt and impact and effects of the attack, you would instantly recoil and reconsider your actions.
If it were impossible for you to do something to another without it also being done instantly to you, you would realize that you cannot do anything harmful without hurting yourself. You would literally find it insane to suggest that you WON'T be hurt when you hurt someone else. You would know this is not true, and that you are guaranteed to suffer when you inflict suffering.
The motivation this gives you then is the clear sanity that, in order to be happy and loved, your only option is to give happiness and love to others. If for an instant you choose to give hurt or to make guilty, you know that you will instantly feel awful and would be quick to stop yourself. If the very dagger with which you attempt to pierce the heart of a brother literally sticks into your own body, you would stop in your tracks.
In truth, when you are more aware of reality, you actually are in touch with this law. It may not appear to apply at the physical level, but it does apply at the level of mind. Any seeming psychological state of attack which you think you project onto another, you do not escape. Any angry attempt to make another guilty reinforces your guilt. Any desire to be murderous and hurtful threatens you and instills fear.
v There IS no escape from the golden rule. The ego counsels that you can easily escape it, even that you can commit the most horrendous attack and come away without remorse or damage. That you can get away with murder. But the only way you would seem to convince yourself that you've done this, is to be in denial.
It requires you to separate yourself off, dis-associate from your brother, form a separate identity which is different and at war, believe that your brother is in no way part of yourself, isolate and imprison yourself in the body, and then perhaps be convinced that your actions won't hurt you. Only by severing yourself from the sonship could you possibly convince yourself that this would work, but at the cost of making you imprisoned and alone.
In truth, your real nature is that you are one with all others. That we are all joined together in sharing as a single family of equality. I am you and you are me and we are each other.
"One brother is all brothers. Every mind contains all minds, for every mind is one. Such is the truth."
Everyone is everyone. We are each individually the whole sonship. Everyone else is a part of your self. Not one single thing can occur against a single individual without it happening to the whole. When one suffers, the whole suffers, because the whole is in every part. We have a holographic relationship and this is the will of God.
The fact is then that if we fall into the ego delusion that we are separate from each other, we will then automatically believe that we can indeed attack without being attacked. And so begins the spiral down the slippery slope to hell in which you believe and then perceive that you are justified in murder, capable of revenge, and can get away with it unaffected. This state of mind itself is mental illness, suffering, self-attack, self-abuse, and self-destructive.
The simple truth then is that everything you give, you are included in the receipt of. Anything you do, you do to yourself. Anything you give or radiate or share or express, is being expressed toward you as well. It may seem on the physical level that something has to leave and travel and be sacrificed and lost, in order to be given or done to another, but in truth you always keep what you
give, because sharing is reality and not separation. To receive what you give is the golden rule and the inescapable law of God. It is functioning even when you don't believe it is functioning. It is functioning when you believe you are getting away with separating yourself off from receiving. It is also the secret of salvation, in the recognition that if you are suffering, you must have done this to yourself. You must have given suffering and then received it, believing that you would escape the receipt.
If you are suffering, you have attempted to attack the sonship. Not just yourself, but everyone. But just as every attack thought, and attitude, angry guilt-mongering, or outright violence, is always an attempt to give yourself death. It makes you unhappy to make others unhappy. It hurts you to hurt them. You cannot escape this. Anything you do to attempt to destroy a son of God will have self-inflicted repercussions. And as such, if you are not at peace, you must have made a wrong decision.
To find salvation therefore we have to learn the simplicity of lesson 125 - that at all times, what I am giving I am receiving. If I do not like what I am experiencing, I must recognize I have chosen it and have given it, and have therefore received it. And I have done this to myself. I must be mistaken if I have given myself suffering, and I made the decision myself, but I want to choose otherwise because I want to be at peace.
This is all tied together. It is the one law of God that everything is always shared, everyone is always included, and you will never escape the consequences of your giving. If want to stop suffering, learn to stop making others suffer. If you want to be happy, give happiness. If you want to feel loved, learn to love. You will heal as you let the Holy Spirit teach you to heal. And you will find God in your brother as you learn that your brother is a part of your shared identity in Christ.
