This inner shouting isn't really shouting; it's unconscious. Even though in Ms. Dog's case, she IS shouting. The internal resistance that the enneagram book talks about isn't about the kind of boundaries we set up to let a person know what is acceptable behavior and what is not.
When I was quoting before, I left out this paragraph:
Quote: When we truly inhabit our Instinctive Center-- fully occupying our body-- it gives us a profound sense of fullness, stability, and autonomy or independence. When we lose contact withour Essence, the personality attempts to "fill in" by providing a false sense of autonomy.
To give us this false sense of autonomy, the personality creates what psychology calls ego boundaries. With ego boundaries, we are able to say, "This is me and this is not me. That out there is not me, but this sensation (or thought or feeling) here is me." We usually believe that these boundaries correspond with our skin and therefore with the dimensions of our real bodies, but this is not always the case.
This is because we are usually sensing habitual tensions, not necessarily the actual contours of our bodies. We may also notice that we have almost no sensation in some parts of our bodies: they feel blank or empty. The truth is that we are always carrying around a felt sense of self that has little to do with how our body actually is, where it is positioned, or wht we are doing. The set of internal tensions that create our unconscious sense of self is the foundation of the personality, the first layer.
The text goes on to say that ego boundaries are of two types, inward and outward. We come to know what outside of us that is NOT us (for example when we get our hair cut, we know we are not cutting off an essential part of ourselves), and we also come to know that things can be inside us but NOT us (for instance, we know that dreams are ours but not US). So far so good.
The book goes on to say that the 8's ego boundary is primarily focused outward. Eights are constantly putting out energy so that nothing can get too close. [This really applies to my bf.] They are very defensive. They want nothing to penetrate their defenses.
However-- and here's where I picked up the original quote--
Quote: Type 1 individuals also hold a boundary against the outside world, but they are far more invested in maintaining their internal boundary. All of us have aspects of ourselves that we do not trust or approve of that make us feel anxious and that we want to defend ourselves from. Ones expend enormous energy trying to hold back certain unconscious inpulses, trying to keep them from getting into consciousness. It's as if 1's were saying to themselves, "I don't want that feeling!"
etc. So the boundary they're talking about is not a boundary against a possible partner. This ego boundary is something Mrs. Doggie has had since she was a child. It's part of her personality and sense of herself. For the 1, the ego boundary is about not letting certain of their impulses come into their own consciousness. Because the 1 is obsessed with perfection, order, and control, I say these impulses are about humanness, vulnerability, the messiness of life.
The third type in this group that the book calls "The Instinctive Triad" is the 9, who has the externally directed ego boundaries of the 8 AND the internally directed ego boundaries of the 1. What this creates is a a passive-aggressive (as honey correctly pointed out) person who spends a lot of energy resisting reality on both fronts! Sometimes they take the position, as my late H did, of just seeing all points of view and agreeing with everyone (but not DOING much).
Underneath everything, for the 1, 8, and 9 is rage.
Whew! Does this help clarify? (I'm certainly learning a lot!)
