I am, I suspect, going to be
very much the odd man out. But spirituality plays no more part in my MA training than it did in my ski racing training when I did that.
I take as my models MAists such as Bushi Matsumura, Chotoku Kyan, and Choki Motobu, who made it clear in both their words and deeds that their MA was, for them, first and foremost a set of fighting skills. A set of physical actions which had a particular kind of physical result.
I went to junior high school and high school with a disproportionate number of aggressive bullies who make Dudley Dursley look like the bookies' favorite for this year's Nobel Prize in physics, and to university in a very dangerous, unpredictable city where many nice, ordinary people, people much like me, travelled armed to the teeth for personal self-protection. So, many decades before I started studying MAs, I was in the market for any kind of self-defense system which would allow me to defend myself effectively and—this is a little hard to explain concisely—
elegantly, in the sense that a forced mate in chess is elegant. I wanted a technique set that I could apply to a variety of violent attacking moves that would, all other things being equal (no weapons, equal shares of luck, etc) give me heavy odds-up on my attacker and force him out of the fight, badly injured most likely, regardless of what he did after throwing the first punch. I also had weapons at hand, but those were for situations where I had lead time to deploy them prior to an attack and very likely scare it off (as happened on several occasions—it's remarkable how fast the sight of eighteen inches of inch-long motorcycle chain link in your would-be victim's hand convinces you to that the path of virtue, arduous though it is, is definitely the better path!

).
When I finally started formal MA training, many decades later, my views and expectations hadn't changed. MA = CQ H2H SD. For many people it has other dimensions, I know, and that's fine; I do calligraphy, and used to know calligraphers who viewed calligraphy as a spiritual exercise. And there are probably ski racers who think of ski racing that way... and if you think it is, then, in a sense, it
is. It's just... I
don't, and so for me, it isn't.
