Think lightly of yourself, and deeply of the World - Miyamoto Musashi

You win in battles with the timing in the Void born of the timing of cunning by knowing the enemies' timing, and this using a timing which the enemy does not expect. All the five books are chiefly concerned with timing. You must train sufficiently to appreciate all this.

If you do not chase in directly toward the place where your opponents have gathered, you will not make progress. And, if you start thinking about the direction from which your opponents will come, your mind will be waiting and you will have the same result. Parry your opponents' rhythm, know where they will crumble, and you will have the victory.

In the construction of houses, choice of woods is made. Straight un-knotted timber of good appearance is used for the revealed pillars, straight timber with small defects is used for the inner pillars. Timbers of the finest appearance, even if a little weak, is used for the thresholds, lintels, doors, and sliding doors, and so on. Good strong timber, though it be gnarled and knotted, can always be used discreetly in construction.
