Anyway, I feel like the little part is a part that had it's life or freedom or whatever threatened (or perception of such). That shit the reptilian brain takes care of. Logic doesn't really come into play. So I feel like as the person grows, this part can't grow with it because it has learned that if ABC happens that logic won't help and assigns it to the reptilian brain to take care of. The reptilian brain thinks nothing, just reacts. That is what I feel like a 'part' is. It takes a safe place for that part to grow. That is what I attempt to use my SELF for. My unaffected soul (or whatever) that I have spent much time nurturing and trusting.
