I have now come to terms with the various views on the various aspects of Aikido on this forum and have found when I say certain things like 'Spiritual' then others think they know what I'm saying and yet I find they have no idea of what I'm saying for it is down to that word and me not explaining what I mean by it.
Firstly let me state what I mean by principle: A rule to be adhered to and followed based on a truth.
Firstly, let me ask: how you define "truth"?
Energy also goes around a center no different to one planet or satellite in orbit and thus we have circles in Aikido and they are REAL.
BTW, have you ever heard about 1st Kepler Law.?
