Just as an observation: A lot of the talk about "Internal Strength" and "Aiki", etc., appears sort of new and exotic to a lot of Aikidoists, but I noticed in "This is Aikido" and other early publications, there was a lot of discussion about "ki strength", "kokyu", and so on. They were talking about the same thing.
Good post, Mike. It's easy to tell that you're always thinking and studying with a humble heart. The more I studied Ki, the more I found that they were talking about the same thing.
