You might be angry with someone, you might be upset and annoyed about what they're doing or how they're treating you or others, but here's the secret.
There is no such thing as genuine anger.
Anger always has a secret motive of USING the other person to get rid of YOUR own sin and guilt. Always.
It's very convenient that anger comes across as though you are justified, outraged, offended, annoyed, as though it's entirely someone else who is wrong and not you.
And even in the midst of that anger or upset you will feel all hurt and victimized and unfairly treated, making it seem like this experience is something you totally do not want and have not asked for. You even think you want to get rid of the anger and make it go away. Except you don't.
It serves your secret plan to get rid of your deeper sin, which you've made unconscious to yourself.
You might complain, you might blame, but you're getting a huge benefit by maintaining this state of anger and upset.
You WANT other people to attack you, you WANT other people to hurt you, and you WANT them to do things to you so that you will have a great opportunity to find them guilty.
You'll then jump at the chance to accuse them, regardless of how upset you are or how much you perceive that you don't want this to be happening. You DO want it to be happening.
You are using other people to hurt you so that you can get revenge and get rid of your own sin. You're trying to make them wrong, think of them as the one who is wrong or bad, so that you have this opportunity.
So in your anger, it might seem as though you're upset because of what they are doing to YOU. But what about what you are doing to THEM?
Your desire to see them as wrong is an attack. Your desire to find them guilty is an attack. Your desire to pin the blame on them is an attack. This hardly justifies your innocence.
No-one else is ever the real cause of your upset. No-one else ever attacks you or makes you experience effects. No-one else puts the effects into you or into your body. No-one can do anything to you but your own mind.
You have to own up to this and admit that YOU believe you are sinful and guilty, regardless of whether other people seem to be accusing you. YOU believe it. And you need to undo that belief (go to the Atonement) if you are to be at peace.
Then having forgiven yourself for what you did not REALLY do (sin is not real), you'll be able to recognize that this other person was innocent all along, they were COMPLETELY uninvolved in what you were experiencing. They didn't cause any of it. You were just using them and doing it to yourself.
