But I thought this was a discussion about O Sensei allegedly always showing the principle of in yo ho as evidenced by him leaving one hand dangling. I would suggest that from close examination of the videos of O Sensei that he does so the minority of the time and he does so basically to show off. As if he was saying, look my timing is so perfect that I can throw with a fan, while standing on one foot, with my other hand not even used.
So. What was it that allowed him to get away with "showing off" in that manner? Just excellent timing? Or was there more going on?
