The first part is an attack on application demo's we see all the time on Youtube-- without shaking power most of them are useless.
The second part is a challenge to all the people who make a distinction between long power and short power. The issue came up in Taiwan talking to Marcus Brinkman and Formosa Neijia, and it is in Nam Park's bagua books too. It's a pretty common way of talking about internal power. The distinction between long power and short power certainly is effective for fighting, there is no conflict here. My challenge is for them to explain how they can do it without creating an on-off switch in their power. I argue that short power needs a root and is thus vulnerable to uprooting. In short, the theory of long and short power does not conform to the Internal Classics idea that, "I know you, but you don't know me."
In putting out this challenge it is my hope that I can learn more about my own limitations, no doubt they are legion. Let the sparks fly.
