It's very simple. God is the ONLY cause of you. God is the ONLY cause of anyone. Everyone who exists is solely caused by God and NOTHING else. Whatever God wills that we all be, we are that, and even we have no say in this.
We are all totally EQUAL and next to each other, and God is above. God creates me fully and creates you fully. I do not create you, and you do not create me. It is nonsense to suggest that I am your creator or that you have caused me to exist.
This means that your brothers are NOT the cause of you. Nor is the world. Nor is the body. NOTHING ELSE can EVER cause you. Not one single person in the world is causing you right now, nor who has ever caused you, nor have you ever caused anyone.
When you believe someone is at fault or doing something to you, you MUST be confused about who your creator is. Whoever creates you causes you. No-one else has any input to this or any power over you. To believe someone is causing you is to believe you are NOT caused by God. To blame someone is to reject God as your creator.
Forgiveness then can very simply entail deprogramming yourself from ANY belief that ANYTHING other than God has power over you. This is the same as saying you should use the power of denial to deny anything NOT of God ANY POWER over you. That includes denying that your brother has any power over you, or that you have power over anyone.
The EGO is the confusion about cause and effect, about who your creator is, and therefore where CAUSE is coming from. If you assign cause to your brothers, or to the world, or to the body, then you are confused. They are NOT the cause of you in any way. When you believe cause is outside of you making you its effect, or you are at the effect of the world, you are claiming that the world is your creator.
You DO actually have creations which YOU HAVE caused, which are the living beings in heaven that you co-created with God and your brothers. These are not the people of the world. You DO have power over these beings because you are the CO-CREATOR of them. But you have created them by giving them freedom, just as God has with you.
If in any way right now you think that some person is doing something to you, or some company, or some group, or something in the body, or some aspect of the world, or anything at all in this dream, then you ARE MISTAKEN.
The ego will then form notions of a kind of cord or connection or chain or cause and effect, between you and others, between you and the body, or you and the world. It will suggest there is a tie or bridge across which stuff from another person "comes into you" and "does things to you" or "makes you" or changes your emotions or induces reactions in you. The belief in these artificial cause-effect relationships have to be SEVERED.
Whenever you are mistaken about causality you will find a belief in your mind that someone or something has kind of latched onto you, is outside you, causing you from the outside in, and now you are at its effect. This is NOT true. This belief has to be undone.
You can simply do this by just looking at the beliefs you DO have about these horizontal cause-effect relationships, and UNDOING your belief in them.
I am not being caused by that person. That person is not doing anything to me. I am not at the effect of them. They are not responsible for how I feel. They are not making me upset. They are not doing anything to me. They are not the cause of my feelings. They have not attacked me. They are doing NOTHING to me.
You can see then that this leads to the fact that your brother is innocent, because if they truly are NOT CAUSING you at all, then you cannot claim that they are in ANY WAY sinful, guilty, wrong, bad, evil or attacking. So they must be innocent. Sorting out the fact that they are NOT the ones doing anything to you, helps you to see their innocence and yours, and places responsibility for sight back your own court.
It is also important to affirm that you are not doing anything to anyone else. I am not attacking them. I am not hurting them. I am not abusing anyone. I am not causing anyone to feel anything. I am not making anyone upset. I am not responsible for anyone feels. I am not making anyone sick or afraid. I am not attacking anyone. This is simply because YOU are innocent. You CANNOT DO ANYTHING TO ANYONE.
God himself PROTECTS everyone by his will. No-one but him can touch his children. His children CANNOT hurt each other in reality. This is the simplicity of forgiveness and atonement. Simply putting cause and effect back into their proper place, being willing to be forever an effect of God, and realizing that LOVE is all that you can actually share with anyone.
"It is God's Will that nothing touch His Son except Himself, and nothing else comes nigh unto him. He is as safe from pain as God Himself, Who watches over him in everything" "I am forever an Effect of God."
"Father, I was created in Your Mind, a holy Thought that never left its home. I am forever Your Effect, and You forever and forever are my Cause. As You created me I have remained. Where You established me I still abide, and all Your attributes abide in me because it is Your Will to have a Son so like his Cause that Cause and Its Effect are indistinguishable. Let me know that I am an Effect of God, and so I have the power to create like You. And as it is in Heaven, so on earth. Your plan I follow here, and at the end I know that You will gather Your Effects into the tranquil Heaven of Your Love, where earth will disappear, and separate things unite in glory as the Son of God."
"I am not the victim of the world I see."
"How can I be the victim of a world which can be completely undone if I so choose? My chains are loosened. I can drop them off merely by desiring to do so. The prison door is open. I can leave it simply by walking out. Nothing holds me in this world. Only my wish to stay keeps me a prisoner. I would give up insane wishes, and walk into the sunlight at last."
"Here is the perfect statement of my freedom. I am under no laws but God's. I am constantly tempted to make up other laws, and give them power over me. I suffer only because of my belief in them. They have no real effect on me at all. I am perfectly free of the effects of all laws save God's. And His are the laws of freedom."I am entitled to miracles because I am under no laws but God's. His laws release me from all grievances, and replace them with miracles.
