I wouldn't use the word mundane but I agree with you in principle on that point. Martial arts were simply the way you lived and trained everyday...nothing special or magical. The discipline you obtained through training was integral to your success as a warrior and in todays thinking that translates into developing "good character"-as obviously we don't go around hacking people with swords, or fighting the our farms, etc.. Hence, we emphasize the budo aspects of our training. Many martial artists today try to separate the two but you can't escape it totally (discipline in the ring dose translate to discipline in other areas-inmost cases)...and in any competition, even to the death, the more disciplined and passionate fighter does have the advantage-whether he is of good character or not.
