When people say that internal doesn't exist, ore there are no hidden, or closed-door stuff, or "high level", etc.
My teacher says,"Yes, but what have they seen? Who have they met, and felt, and to what degree?"
So, have any of you seen, met, and felt, something that was extraordiary, that boggled the mind, amazed you, and made you a firm believer that Gung-Fu, REAL Gung-Fu, and skills that you thought might have been fantasy, really do exist?
