Broken bones mean I have to slow my training down to heal. So I'd rather not, thank you. Bad enough I had to delay testing and take three weeks off of training for a sprained knee....
I was kidding about the bones and I know just what you're saying. I've pretty much given up skiing nowadays for the simple reason that I've never damaged my knees and I want to keep it that way. Meanwhile, all around me, there are few people here in town that don't have ski-damaged knees. Who needs it.
Have you see his excercise with the jo where two ukes each hold and end and you send energy in a wave along it to move them either forward or back? The excercise originally posted is similar. I have not yet really given thought to what physically is going on inside when I do this I only know I visualize the connection which I feel through the hip closes to uke extending to my center as a line of energy. And I just twist that line into a wave that sends uke either forward or back rather like sending a wave along a water bed to move an object at the other end....
I don't know anything about a "wave". Can you describe what a "wave" is, as you see it, in regard to this demo?
OK, so there's a jo and "two ukes each hold an end and you send energy in a wave along it to move them either forward or back
". Notice how incomplete your description is... and that might be a reflection of how you saw the demonstration, so let's try to clean up the description a bit:
Two Ukes are holding a jo.... but aren't they perhaps pushing or pulling on the jo? That's critical in the same way that Ikeda Sensei makes certain that Uke is physically doing something to form a good connection with him. If Uke does not attack in such a way as to form a good connection, then you have to atemi or something in order to initiate *something* in order to form a connection to Uke's center.
In the case of the two Ukes holding the jo, we have to get them to push or pull so that they form a "unit". Then, no matter how outwardly casual we are, if we put our hands on the jo, we still must do it in such a way that the jo becomes part of our own unit. Become "one with the jo" and you automatically become one with the two centers of the Uke's. Now we're back to that basic skill of paths/lines/connections which you have to develop, but if you have that skill you can "feel" for the center of one Uke and then the other; sometimes both at the same time, but it depends on their positions. You have a good connection, you move their center with your center.
Does that help?
