Oh Mongo, do behave!
I was getting some instruction from a guest instructor, Sensei "Butch" Chernofski who ofter teaches in NYC Aikikai.
With practice in kokyu doza he got me to use no strength, which was no fun at all.
So just for fun, as I explained how it felt like nothing at all, I grabbed the shoulders of his gi and lifted him to show him how kokyu doza usually feels with strength. He smiled and said that works, but actually I am more helpless when you said it felt like nothing.
So now, I do nothing, more and more.
ONE WHO EATS TREES.
