Re: Ki is Kindness.
I understand what you are saying, and I think it's a very nice ambition (but see, "Are we that good?"). I also understand the underlying values reflect a prominent view in some circles, and I don't want to focus on (or dispute) that.
However, while I'm seldom sure what folks mean when they talk about "ki," the statement "ki is kindness" I find about as easy to understand as the statement "heat energy tastes good."
Do you think that budo styles which teach how to harm are devoid of "ki?"
Did Takeda train his students, including O Sensei, how to use ki?
If so, then the spiritual element of aikido to which you're alluding seems like it needs a different conceptual scaffolding.
I may, of course, be mistaken.
