So, every feeling you have, every reaction you have, you choose to have, on your own. And it has nothing to do with stimuli or what other people are doing or what happens.
So you're really walking around with a blank slate, happy, having absolutely no reason to be upset, and then you literally are picking something out of the environment and saying, AHA, I think I'm going to claim that I'm triggered by that, I'm going to create a reaction, I'm going to choose to be unhappy.
So then you do.
And it had nothing to do with what happened outside you.
So really, you're this kind of walking talking reacto-machine which just fires random reactions all over the place for no particular reason.
If nothing outside of you is really to blame or really has anything to do with why you are upset, and your upset is just YOUR OWN STUFF which you need to be fully responsible for, then you quite literally are manufacturing every interpretation and every reactive experience that you're experiencing, inside yourself, by yourself.
So once you start to take responsibility for this, then this is breaking the spell. It's breaking the connection between something happening and you then having a reaction and blaming the causality of it on the thing - "it caused me to have an effect" gets broken.
Once that starts to be broken and you stop CONNECTING or JOINING fake external causes/triggers with internal effects, and you realize the cause is IN YOU not out there, now you're in a different scenario. You cause all of the effects you are experiencing, AND you are causing all of what SEEM to be the effects of outside causes. You are causing your own reactions!
So now you can stop having reactions, by choosing not to. Or you can at least own up to being the one who is choosing to have it. And what begins to happen as you begin to 'stop' making the tie between external causes and internal effects, and reclaim the tie between internal causes and internal effects, is you start to realize they are not and don't need to be joined.
So that means, if you wish, on a whim, you could decide NOT to have any reaction whatsoever to something you'd normally react to. And conversely, you could decide to react on purpose to something ridiculous that would not normally call for a reaction (a bit harder to do without the unconscious element).
So as you practice this you grow stronger in the awareness that your reactions aren't actually caused by anything outside you, and that you can - at will - choose not to have them. By owning them you disconnect from the ego and automatically choose Holy Spirit. And by severing the tie between external causes and internal effects you now regain access to your inner causality.
So how about you then learn to simply choose to no longer PRETEND to be at the effect of external causes, and maybe you ADMIT that you cannot BE affected by anything external WITHOUT YOUR CONSENT (including death). And then you find yourself laughing because you realize you're being upset for absolutely no reason and because of no cause, which gives way to laughing for absolutely no reason and with no cause. Because when YOU are the cause, you are aligned with GOD the Cause, which is nothing but joyful.
