A few of us had a nice conversation w seki sensei one summer, and he said I think basically the same thing.
We have to define for ourselves, what it is we want. Jutsu or do... Self preservation, or self improvement
Seki, for all that I loved training with him, has never been much of a thinker.
"Jutsu" doesn't mean self preservation, just as "do" doesn't mean self improvement.
