Having experienced "Aiki" all I can say is that I was a fool to think any Aikido Waza I had extensive experience in expressed any kind of internal "power" in the 25+ years I have been around. Thank goodness it's something I can learn, and incorporate into Shoji Nishio's Aikido without continuing to argue over the semantics and philosophy of who is "aiki'er than thou".
WAZA yourselves out brothers and sisters...seriously. I'll just be over on the other side of the mat doing my thing. Hopefully someday I'll know enough to share it with you.
A lot of wasted years there, my friend.
Hope you find what you're looking for... and have the confidence to stand behind it!
