The Sword

Samurai_with_swordAlthough you see the sword that moves to strike you, if your mind is not detained by it and you meet the rhythm of the advancing sword; if you do not think of striking your opponent and no thoughts or judgments remain; if the instant you see the swinging sword your mind is not the least bit detained and you move straight in and wrench the sword away from him; the sword that was going to cut you down will become your own, and, contrarily, will be the sword that cuts down your opponent.
