Re: Why bother keeping Aikido 'pure'?
It is my understanding that Ueshiba did not teach IP because he believed it was a spiritually derived gift and not a learned skill. He admonished Tohei for drinking because the spirit of aiki would not come into him if he did. My statements are not exact, I am sure the scholars here can probably provide ample correction. I believe the first statement is from the forward of Tohei’s This is Aikido (I don’t have a copy and can’t find a reprint of the forward, 2nd edition apparently), I could be conflating this with information gleaned elsewhere; I’ll check with sensei and provide follow up. Sorry for the lack of scholarly precision and erudition.
