A master swordsman relayed the following narrative in his old age: “Training over a lifetime involves various phases. Unskilled men at the lowest level will make little progress at the start of their training, and their ineptness is obvious to themselves and others. Men at this level are of no use. Those at the middle level are still unusable, but are aware of their deficiencies, and are able to identify defects in others. Men at the upper level have useful skills, are proud of their degree of proficiency, enjoy the praise, and empathize with those who lack ability. This level has worth.

“However, men who have traversed to an even higher stage of expertise in swordsmanship will pretend that they are unknowing, but those around them will sense that they have unmatched skill. This is probably the zenith of attainment for most men. Beyond this extends the ultimate realm that is impossible to describe in words. It becomes clear to the master that this realm is boundless and his skill can never be perfect. With this realization, the master, being fully conscious of his imperfections, is neither conceited nor contemptuous, but continues traveling the path.”

Lord Yagyū once said, “I do not know how to defeat others. All I know is the path to defeat myself. Today one must be better than yesterday, and tomorrow better than today. The pursuit of perfection is a lifelong quest that has no end.”
