because i wasn't talking about jin.
Sure you were. You just don't know it.
P.m. me and let's set up a meeting so you can show me your "system". I've seen tapes of what Sam Chin does. I know what he does. That's not the same thing that your video shows that you do. Why is your "system" different from what Sam Chin does? If you don't mind, please explain with something other than just buzzwords and vague terms like "Yin-Yang".
Everything is Yin-Yang. It's like saying "String Theory" or "Angular Momentum". Internal strength has some fairly physical phenomena, despite many peoples' belief that there are somehow different ways of doing these things that no one but paying acolytes can understand.
