I think that what Phi is referring to is that "mind" and "intent" are often distinguished between in Japanese and Chinese culture, and that the differences are important to many of the martial explanations given in Chinese arts...and by Morihei Ueshiba.
Mix the two and some (many?) of those classical explanations make much less sense.
That's, to my mind, a very critical point for the explanation and understanding of what's internal in aikido, too, Chris.
My language skills and expertise are not sufficient, to elaborate further on this. But I'd love to see you doing this once.
"In my mind my intention meets the intention of others, aiki."
