The problem we have though is that once we get into the way of perceiving, the mindset, where we actually are quite adamant about how it is someone else who is wrong, it may not even occur to us that we need to forgive or that there is any other way to look at this. We can get so absorbed with anger and reactions and frustrations, that compound and increase the sense that the other person is wrong. It's all their fault. And we may not even REALIZE that we are actually experiencing being a victim right now.
Often when we are victims we are actually in a state of anger or frustrations and projection and that means that we're really really convinced that all of the 'problem' is outside of ourselves. Like, literally, it seems like it's got nothing to do with us. And we don't even recognize that we feel victimized by whatever it is we think the other person is doing wrong. Anger and frustration for example are quite strong energies which seem justified and which aren't usually interpreted as victimhood.
Victimhood is often equated with the experience and perhaps the acknowledgement that something is happening against your will - at least the awareness that you are suffering. When you are upset and pissed off at how wrong the other person is, you may not even have that awareness, because you feel like you WANT to feel angry and SHOULD feel angry, rather than that that you are actually suffering in a state of victim consciousness.
So an early step is, to recognize, if you are angry and upset, you most likely - pretty much definitely - are experiencing the situation as a VICTIM, and that means you are actively SEEING yourself as a victim, and playing the ROLE of a victim, and are actually CHOOSING that role. And you don't have to.
Just because you currently are really passionate about how the other is 'wrong', that doesn't mean you are in your right mind. You don't have peace, so something is amiss. Do you want peace, or do you want to keep being angry and outraged and justified in doing so, as a victim? Do you want to keep suffering? And, is the solution to your suffering that the other person changes and stops doing what they're doing, OR is it that YOU actually need to change yourself, so that you stop experiencing the situation as a victim? That's not so easy to admit to, or to have a willingness to pursue. It's much easier to skapegoat the other person and to expect them to be the one who is meant to change. That's the ego's form of forgiveness.
And there's a trap you can easily fall into. In the situation, just based on an evaluation of what's happening and how most people would view it, sometimes the other person IS seeming to be wrong, or IS severely mistaken. Maybe they are lying, maybe they are deluded, maybe they are attacking you, etc... so there is now 'evidence' that they are wrong. And this is a severe trap because now there is a risk that you will be so convinced they are wrong based on the situation, that this JUSTIFIES even more you condemning them for being wrong. And this becomes even more of an unconscious reaction. It wouldn't be so hard to get out of this if they were more obviously right.
But when even the situation itself clearly shows that the other is wrong/mistaken, it's very much harder to stop yourself from using that to judge them. So they're wrong, okay, that's fine, but does that mean you have to be right about it? Do you have to make them wrong for being wrong? What about recognizing they are wrong, but seeing that this wrongness is a mistake that calls for FORGIVENESS, rather than you conveniently using is to ATTACK them for it? Once you enter into attacking someone for them being 'actually wrong', you are falling into the ego's trap and likely will become even more upset.
So stop. Step back. And have this little willingness..... maybe it's ME that is mistaken. Maybe I am projecting. Maybe the other person is not as wrong as I'm making out. Maybe the other person IS wrong but I don't have to react to that wrongness with more mistakes. Maybe what I see in them IS my stuff. Maybe it's not actually their own wrongness. Maybe all the guilt I see in them, even their sickness, even their fear, even their delusions, even their lies, even their attacks, what if that is actually MINE? And what if I need to take that back and seek true forgiveness for it from Holy Spirit?
This is the beginning of taking responsibility. No matter how the situation seems, whatever you are seeing IN it, whatever you see IN the person, whatever you think is THEIRS and not yours, IT IS YOURS. Take it back. Own it. Then take it to Holy Spirit for correction. The other person is INNOCENT. They were just holding onto your guilt FOR you, so that you could disown it. Get honest as fast as you can.
