Until there is a general consensus about what is meant by the word 'internal' it's silly to keep talking about it. We should just be talking about the problem, as simply as possible, and work our way out from there.
I guess we better stop talking about Aikido too, because there's no general consensus there, either.
OTOH, looking through through the thread I see that the great majority of people participating have a basic consensus about what there're doing, but are expressing that with varying degrees of success (I'm not saying that I would do better).
And that's my drive by for the day.
