Further exploration of "O-Sensei's Cupped Hand"

 

As I was exploring the concept of quickly unbalancing uke from katatedori hand grabs, I came across this photo of Aikido Founder Morihei Ueshiba from his 1938 technical manual "Budo". This image has provided great insight into the subtleties of unbalancing maneuvers and assurance that I was on the right path in developing the "Zone Theory of Aikido".
