I'm not translating the word when I say that. I'm replacing the concept. In most cases where Qi (Ki) is referenced in JMA, the most realistic explanation of what's being done isn't really "extending energy", but changing body structure through changing intent. I still use the term "Ki", but my students understand it to be a shorthand for those structural and intentional concepts.And just an FYI, anyone claiming Qi is proper use of structure, posture, muscle etc. Is incorrect, that terms are Li & Jin, and anything involving concentration, thought or the mind is Yi. Qi simply means energy.
