My point is just that qigong is a tool that is used in many traditions, one of them being aikido.
I'm not sure what you are talking about, when you use the term "qi gong"?
We agree that qi gong is not a certain school or a certain tradition. Especially since the term qi gong itself is not very old.
When I use the term "qi gong" I refer to the system of working with jing, qi and shen as it is known in the daoist tradition. Even if there are specific distinctions between different schools and branches and allthough the daoist qi gong differs in certain aspects from qi gong used in TCM, the system altogether is not a tool I see "used in many tradtions".
Especially I don't find it in most of the ways of practicing aikidō I experienced over the years.
What I understand as qi gong has a very specific background in Daoist tradition and needs specific forms of body work. (Which, I think, have strong connections to what Dan teaches. At least in my practice both seem to fit perfectly together.)
