And he states that aiki is a technique ...
He states that aiki is both body conditioning and
applied application. He is discussing a rather deep subject. He is correct. Unfortunately I have never seen this demonstrated "in its fullness"
much less taught or discussed by anyone in Aikido or Daito ryu.
..every waza has an essence, a certain substance. If you find this essence of a waza and adapt it to your own body, feelings, character, you can bring the waza to life. But still the waza is independent of you. It still exists without you.
I think this is foundational error. It is the essence of what is happening in the body that makes all waza happen and is universal. The rest is window dressing. Your entire art is based on being techniqueless.
