Re: The Catalyst of Aikido, Non-Resistance.
None of it is spiritual and the giants who could actually do it- always said it was NOT SPIRITUAL.
Those who can't do it...have to default to something, some reason why they can't. So they make it this "out there" thing impossible for them to achieve. Therefore they can argue it's merits all day long as to varying degrees of their own failures.
The principles to achieve it require a great deal of body work to change the body and mind/body, then the movements that make it happen become rational secondary results.
Everyone else just keeps turning and evading...missing the real goods in their entirety.
