Sunday evening sensei introduced some exercises to us that come from this Internal Power concept. I have to admit I found them rather fascinating. Like flexing muscles I had not really realized were there. The effect on uke was rather dramatic when you got it just right.....I'm looking forward to continuing the exploration.
If Garth hasn't already, I hope he gets a chance to see/feel what people like Mike, Dan, Ark are doing - as they are teaching IS things outside of martial art specific paradigms. Even going a step further and trying to get a feel of what the big dogs in Chinese systems such as Chen Xao Wang of Chen Taiji are doing. Get exposed to the talent pool that's out there. Mainstream aikido has a lot of work to do to get it back - but if there's any art that should have it ... aikido would be one.
