So much discussion on power I thought I'd give another perspective.
As I see it following the desire for power and more power is a fools errand as far as Aikido is concerned. As I see it I see people debating and believing they are achieving something yet to me no matter how much they try to justify this search they are unaware they are merely standing still or even going backwards.
Can anyone describe what power is spiritually?
A waterfall has no "desire for power and more power." Yet it is, undeniably, powerful. Similarly, that place at the meeting of heaven and earth, that place where the Harmony of the Universe is realized...there is great power at that place where O Sensei stood.
Whether you seek power or not, you'll find it if you go far enough down the path. If you don't, maybe you're on the wrong path.
