My own teacher goes as far to say that 'aikido is a series of dynamic ki development exercises'. I think I am at a point where I can see the truth in this. These Tohei created/inspired exercises are definitely a force for positive learning in aikido. I can't imagine having reached the understanding I have without them (an impossible hypothisis to verify).
Hi Mark -
I like that. It's gratifying to know that internal training in Aikido is alive and well; and not just in my small corner of the world.
