If you are caught up in an emotional interaction with someone, upset by them or about them or struggling to forgive them, trying doing a forgiveness where you sever the connection of cause and effect between you.
By that I mean, make statements which completely cancel and undo all ideas about how the person is *causing* anything to happen to you whatsoever, and vice versa.
That person is not doing anything to me. That person has not upset me. That person isn't the cause of my upset. That person has not affected me. My feelings are not caused by that person. That person has no power over me. That person did not make me be this way. I am not dependent on that person to be happy. I don't need that person to treat me a certain way. I am not at the effect of that person.
Also, I have not done anything to that person. Everything they are experiencing is their own choice. I have not caused them to be upset. I am not responsible for their happiness. I have not made them be the way they are. I did not influence them. I have not hurt them. They are not at the effect of me.
Come up with as many statements like this as you can think of to reflect on how neither of you have caused the other anything whatsoever.
As you do this you should notice a sense of relief and also a growing clarity that you are both innocent, you are both powerful, you are both responsible for yourselves, and you are both free of the illusions relating to how you are doing stuff to each other.
The illusion that you are doing stuff to each other is entirely unreal. The ego can only attack itself. The ego in the other person can only attack itself. The ego in you can only attack yourself. Anywhere that it seems that something goes from one person to another is an illusion, just an appearance that both of you are doing something similar, or that you're each triggering off your own upsets. Neither of you are really causing the other to experience anything at all. You are both in your own ego's private worlds, interacting with your self.
Take full responsibility for everything you have done to yourself. Recognize they are responsible for everything they have done to themselves. Recognize that nothing has TRANSFERRED between you, neither of you has CAUSED the other to do or feel or experience anything, and both of you are entirely free of the ego influence of each other.
Whats mine is mine. What's theirs is theirs. This at least applies to the ego because egos are separate. What is OURS is OURS, which is love.
Only love is a shared experience. Only love can be joined in. Only love can be mutual and only love can be a real relationship in which two people are connected or communicating. All of the other stuff, all of the ego expressions, are not relationship or communication. They are just noise that each person is making from themselves about themselves to themselves.
No-one has ever done anything to anyone else. Everyone is doing everything to themselves. Nothing has really happened.
