I agree completely. I was just trying to determine the boundaries of qigong. I am amazed how flexible it is, and how you can accomplish something almost no matter what restrictions you have. I have been doing taiji for over eight years now, and so have some familiarity with neigong (internal)systems. When I was younger I also did a lot of work with waigong (external) arts, so I am just trying to fit everything together into a coherent picture. Thanks for your insights.
