By compromised structure and alignment I don't mean that you're disrupted. I mean that you don't rely as much on posture. Even in postures that would not seem stable, you can be stable.
It's hard for me to get at this. But I think what you are saying is that it may simply appear
that you are not stable, when in reality you are stable. Is that correct?
Appearance really doesn't matter when we get down to the practicality of what we are doing. As long as you are stable, I would say you are stable, even if it looks/seems like you shouldn't be.
Now if you are physically stable, we can ask, "what is making you stable?" Is it your body, or is it some other "force"? If it is your body (your structure) making you stable (aligning), it is a body skill we are talking about. If it is some other "force", then we can take your body out of the equation, and we'll need a new definition, one that doesn't include "Body skill".
So appearance aside, is the body making itself physically stable, or is some other force making to body stable?
