Even if he has no natural ability, a samurai must train assiduously in both skills to a degree appropriate to his status..... The samurai pursues martial strategy, however, in order to excel in everything, be it winning a duel or winning a combat with several men, be it for the benefit of your master or to establish your own reputation and distinguish yourself. The samurai does these things through the virtue of strategy. Some people may think that even if you learn martial arts, they will be useless in actual battles. That may be so, but the true spirit of martial strategy requires that you train to be useful at any moment and teach men so that they may become useful in everything.
