At the very root of the ego thought system is something extremely simple, which is the foundation of the entire thought system. It's even more fundamental than the idea of sin.
In Heaven, God is the cause of you, and you are the effect of Him. But you attempted to REVERSE THIS. This is THE ONLY PROBLEM IN ALL OF EXISTENCE.
Your belief that you are the cause of God, and that he is the effect of you, is the ENTIRE PROBLEM. This is the authority problem. It is the basis of the idea of sin - which is the idea that you caused God and produced effects in him and therefore defined and changed him against His will.
Absolutely EVERY possible dynamic and situation you find yourself in in life, all your encounters with people, all forms of sickness and suffering, and every possible problem or upset you might experience, are ALL ENTIRELY BASED on the reversal of cause and effect. That is their FOUNDATION.
There is one problem.
And this one problem needs only ONE SOLUTION.
It is a single solution, a single lesson, which applies to EVERY situation no matter the form.
This one problem is ALL that you need to correct. Every forgiveness process, if it works at all, MUST accomplish the correction of CAUSE AND EFFECT. If it doesn't, it is not solving the problem. It doesn't matter what words you use or how you go about this, but ultimately you MUST get the levels back into their divine order. You MUST correct the level confusion and restore God to the rightful position of CAUSE, with you as HIS EFFECT.
Because God caused BOTH you and your brothers EQUALLY, you are BOTH caused by God. This means, a fundamental truth: you are NOT the cause of your brother, and your brother is NOT the cause of you.
Now, the entire ego thought system is based on the belief in cause-effect reversal, and that MEANS that you have a belief that YOU ARE THE CAUSE OF YOUR BROTHER, and that HE IS THE CAUSE OF YOU. This is an ILLUSION. It is the illusion of "horizontal causality". That means, it's the idea of two things on the SAME LEVEL, causing and affecting each other. IT IS NOT TRUE. AT ALL. EVER. ***You can't both be the cause of each other!***
The entire ego world was set up to try to prove and make seem true, the idea of HORIZONTAL CAUSALITY, whereby one thing causes another on the same level. This is built into physical matter. It's built into the laws of physics (chaos). It's built into all egoic encounters with people and problems. They all tempt you to believe that GOD IS NOT THE CAUSE. They are all attempts to shut God (mind) out of the picture and associate mind with FORMS and bodies. This is nothing short of believing that YOUR DREAM IS DREAMING YOU.
This perception, which is false perception, automatically puts you in a position of seeing yourself as a victim. A victim of people, a victim of the world, a victim of the environment, a victim of your body, etc. IF ITS TRUE that there is cause SEPARATE from you in this way, other than God, then you automatically MUST enter a state of threat and danger and fear and attack. This is the basis for justifying all anger. This has to be corrected.
So now it comes down to, "how do I apply the course"? Or, "how do I apply forgiveness"? Well, it boils down to the ONE PROBLEM. If you will just correct ALL FALSE CAUSALITY, which is the idea of horizontal causes and effects, if you will totally CANCEL and UNBELIEVE and WITHDRAW all of those perceptual beliefs in horizontal causes, it will put the cause back into your mind where it belongs.
See, at this level, you are the dreamer of the dream. You are the CAUSE OF THE WORLD. When you perceive or believe that anything IN the world is the CAUSE OF YOU, you have backwards perception and are a victim. The secret of salvation is that you are doing this to yourself. You use the world to attack yourself. If you are not aware that you are the CAUSE of it, that you are dreaming it, you will perceive and believe that the world is hurting you against your will.
So the ONLY FORM OF FORGIVENESS that works and that is needed, is to GET THE CAUSALITY RIGHT. To remember that you are the dreamer of the dream, not the other way around. That there is NO CAUSE in the world. That the world is the EFFECT of your dreaming mind. That means your brother in no way causes you whatsoever. And it also means you in no way cause your brother whatsoever. It also includes realizing your body does not cause you against your will. Your mind has power over the whole universe. "My self is ruler of the universe."
It's quite simple really. Just get the levels back into their proper order. This corrects all level confusion, magic, victimhood and even death. You are the cause of this dream. You have to OWN RESPONSIBILITY for being the cause of EVERYTHING you are experiencing and making happen. This is the only way out of hell. The ONLY WAY to escape victimhood and death by realizing that.... if you do not CHOOSE TO DIE, IT CANNOT HAPPEN. "No one dies without their own consent."
This is what "forgiving" is all about. Own the causality. This is a course in cause, not effect. YOU ARE 100% CAUSAL. You are 0% AFFECTED by what you've caused/made. You are the projector of the world. Projection makes perception. Once you own full responsibility for causing/dreaming, the world can do NOTHING to you against your will. This is how you overcome death and reach resurrection. And in that state you cannot be attacked, victimized, hurt, or suffer in any way. It is literally the end of all suffering because it is THE END OF THE WORLD.
