That is a lot of deep insights for sure!
In NLP, the idea of “parts” can definitely help. The “there’s a part of me that…” thing, NLP actually thinks of it in that way.
Their idea is to go inside and ask that part (the Negator for you) what it’s actually trying to achieve for you by (behavior/state that happens).
That whole idea of how every behavior (no matter how “bad” it is), has a positive intent behind it.
So the key there is to find out what positive intent the negator has (which you’ve start to hit on by the thing of avoiding disappointment).
Sometimes, you can fee that answer back to the part, “By helping me (intent), what is it you’re trying to get for me?”
Keep feeding that answer back until the responses become “Edge of world” language, where the answers can’t go any further.
“Edge of World” answers sometimes have words like “Just”, “Only”,“It’s a fact that” and so on.
Where you can’t easily get to any “deeper” answers and ti starts to just feel like “That’s how it is”.
Apologies for rambling. I’ve been reading a bit more lately from L. Michael Hall’s “The Sourcebook of Magic” and it’s a damn good book.
Loving the progress you’re making!
