Re: Ki Aikido - quote from Gleason Sensei
Tohei's methods were definitely a step in the right direction and Aikido in general is weaker for not keeping them as its base. With that said, he definitely wasn't as clear as he could have been, but then again that's probably by design when you consider his upbringing. If taught correctly, what he was doing definitely makes for better, stronger Aikido.
You see more and more people going back and finding the value in what he was trying to get across (and other methods), but I really don't know what difference it's going to make to the aikido world in general. Most people probably don't feel there is anything wrong with what they're doing anyway, so why change?
It won't be until that type of stuff becomes a set part of the curriculum that you'll see any real changes, and even then only if people are actually getting good instruction and then spending some real time working on those things and testing themselves in some way outside of the waza in the dojo. Unless the Aikikai adopts them as a whole you won't see any major changes ever.
