I took it to be a looser application of meaning rather than some literal translation...along the lines of, say, "teaching is kindness." Obviously the two terms mean different things, but that doesn't mean they can't overlap in some particular context. There are times where teaching is in fact an example of kindness, and there are time where it is not.
I agree with you. My reservation is with the magical thinking of the OP that if I act with ki, my acts will ipso facto be kind acts. Which I see as a variety of bad faith.
