... Assuming I am understanding you correctly, how do wrist locks fit into this view of aikido?
The way we unsterstand and try to practice it, the wristlocks (as other locks and techniques) don't work only on the actual joint.
But through the joint, on the center of the partner.
This can be done using simple mechanics or in other words using the stucture of the human body.
I don't think that our different views depend on our teachers. My teacher of Aikido also practices yawara.
And you describe your practice exactly the way we also do it.
But well ok: If Tissiers Aikido in your eyes is only dancing it can't be helped. So be it.
Only important for me is, whether or not it works.
