正中線 (Seichusen)
A friend and sempai of mine in Japan had been studying this concept recently. He mentioned it in passing and was kind enough to offer me an explanation. Sei chu sen translates as True Centre Line. It is the centre line of the body or in the case of a kamae the line from the lead hand (weapon) to the centre of the spine.
I mention this just as a concept to research, I really have nothing much to say regarding this. I won’t repeat the explanation I received without permission, especially seeing as how my sempai is new to this concept (at least in words) himself. I am just happy that I have friends in Japan to pass this information to me while I am away. So if he is reading, thanks.
If anyone has more information let me know.
