Why did Ueshiba and Shioda (to name two top martial artists) use "ki" in their descriptions? They certainly could demonstrate their martial validity. How many of history's martial masters/grandmasters used ki/chi/jin in their vocabulary and yet could still martially prove their skills and abilities?
(NOTE: It's been stated somewhere that in Chinese, the kanji for ji and chi were different. Ji meant yin/yang while chi was more life energy. But, I'm not entirely sure how accurate or true that is.)
Is it ki/chi/jin or ki/chi/ji ?
Ji being a Chinese or a Japanese pronociation?
Wish you knew which the kanji was!
