I... does anyone have any other insight into other common phrases after "their eyes were opened?"
Well, just the phrase "stance that connects heaven and earth" in itself that gave that thread its name .
Connecting "heaven" and "earth" is something which was taught by different teachers. But only during the last year I came to "make it possible".
My first teacher did research in those aspects, connecting aikido and other arts like tai chi, qigong and also shiatsu.
(Although we did classical hanmi then ...)
... and what Hugh said sounds very familiar ...
