As you heal something about yourself in your mind, you will stop having reactions.
I used to react to the big truckload of fresh live pigs that used to be shipped into the sausage factory across the street. I believed it was awful. It triggered me. I felt angry and guilty. Then I looked at how this was nothing to do with pigs or factories and was about myself. And what I found out was that I felt guilty for catching and killing butterflies when I was younger. And so I did forgiveness on that and reclaimed some real truth about myself, instead of the guilty self I made up. And I was freed from this guilt. And so now when I see the pig truck, there is no reaction. There is nothing TO trigger.
I've also experienced this before where someone would say something to me and it would trigger me. I would feel that what this person said was true, even if I was in denial and claiming it was untrue, and it brought to the surface a reaction of guilt within myself. This feeling of being guilty and wrong and ashamed kept surfacing whenever this thing was said to me. And then I went through some genuine healing and forgiveness and reclaiming of real truth, and this melted some of this guilt away.
The 'guilty identity' that was in me diminished. I stopped BEING the guilt. The sense of 'self' that I had AS the guilty self had transferred more to my true self and I had accepted is at truth. So then when this person came along and said the same things.... ...... ..... nothing happened. No reaction. No feeling that it was even about me. No feeling that it was true. No reaction of guilt. No sense that it could even touch 'me' or do anything to cause me to be upset. Same person, same actions, same statements, no reaction.
So when someone does something to you, or something happens you don't like, it 'triggers' off or shakes up or brings into your awareness an experience of "this makes me feel bad"... in whatever form - generally guilt and shame. And this guilt and shame itself, somehow, by some strange psychological twist, seems like it is associated with YOU, who you are. And so you feel like YOU are this guilty self. You are the guilt. And it comes up inside you and you feel it. And then you're initially like, what the fuck, why did this person just "make me guilty" or "make me afraid". So you blame them for 'causing' this experience to occur, but without noticing that they didn't actually do anything to PUT this experience into you - it was already in you. The guilt-ridden scared self was already in you because you thought that was true about you and was your actual identity.
So all that's happening is your own stuff is coming up into awareness and you're experiencing it and you don't like it so you keep blaming it on someone else. You're particularly annoyed that they keep 'pointing out your flaws' or keep bringing your attention to how guilty you feel. And each time they seem to 'victimize' you it triggers this guilt in you and you feel it and you think that they're doing it to you. They're not. They can't. Only you can experience this guilt as if its what you are. And if you can heal that guilt and stop believing it and stop identifying with it and stop thinking it is true of YOU and that, therefore, it is who you ARE, then you can be free of this guilt. This guilty content. Person comes along and does the same exact action and .... there is no guilt in you to experience... nothing for it to latch onto.... nothing to trigger.... nothing to remind you of how YOU feel about YOURSELF.
This is how you find peace. Undo your guilty ego self and remember who you are in truth and you become invulnerable.
