You quoted my tag line of Shirata: PLace the immovable body in an invincible position...you said
Place the immovable body in the midst of a crowd of attackers and the result will be an immovable stain on the ground.This is not what the immovable body means. It has nothing to do with standing still. Nothing at all. In fact the training that creates the immovable body, is something Ueshiba was deeply immersed in. Push testing constantly.
As I posted to Phi, my statement was meant to be taken as a metaphor, not literally. I take no side in this debate. I had the good fortune to learn from an instructor who placed great emphasis on internal work and continue internal training to this day; though via a different training paradigm than you Dan. As a result my Aikido training is a vehicle by which I can study aspects of both A. and B. in the OP.
