There are a few strands that requiring drawing together to try and understand what the TMA are attempting to do with regards ākokoro no shugyoā (spiritual training).
The samurai were literate but not
eloquent so when the wanted to transcribe subtle martial principles, they would often turn to the best educated to write these idea down on paper; monks. The monks would use the vocabulary with which they were most familiar to get those ideas across. Zanshin -> from Zen, Mushin -> from Zen, fukushiki kokyu/tanden soku (breathing pattern techniques) -> from Zen and many more. Whether samurai were actually attempting to lever Zen and spiritual training into the methods of killing other innocent human beings or is a consequence of one set of very specific terms being used to describe something
very different is debatable.
Many of the ideas of spiritual training started becoming popular in Pax Tokugawa (1603-1868) when samurai progressively became pen pushers in castle offices; how to keep samurai ābattle readyā when there are no opportunities to fight or indeed, need. In some extremely clever thinking the idea became to simply suggest that martial training will make them ābetter peopleā, ādevelop characterā and turn them into super humans of moral, Confucian virtue! I think youāll agree this is simply not the case. If an arrogant, virtue signalling show off of person takes up the TMA, they become an arrogant, virtue signalling, show off who can fight! If an introspective kind, humble person takes up TMAā¦you get the idea.
These events have filtered down to the modern martial arts, colouring them considerably plus the addition of attempts at absolution for post-WW2 crimes.
Iāve recently found a Youtube channel that beautifully expounds the spiritual aspects of swordsmanship.
I donāt think the physical aspects of the TMA have anything particular special about them that induces awakening or spiritual health. For example, I know of a (Rinzai) Zen monastery that uses the chopping of logs with an axe as a spiritual exercise. What I
do think is that TMArtists of long standing
tend to be more introspective and interested in āimproving themselvesā. Then again, others are just c**ts
