A thousand days of training to develop, ten thousand days of training to polish. You must examine all this well. - Miyamoto Musashi

Es esencial pulir diligentemente el intelecto y el espíritu. Una vez que hayáis utilizado vuestro intelecto hasta el punto en el que podéis distinguir lo que es verdad y lo que no lo es en el mundo, en el que podéis decir lo que es bueno y lo que es malo, y cuando ya habéis experimentado varios dominios y ya no podéis ser engañados en absoluto por la gente, vuestro espíritu habrá quedado imbuido del conocimiento y de la sabiduría del arte de la guerra.

What is big is easy to perceive: what is small is difficult to perceive. In short, it is difficult for large numbers of men to change position, so their movements can be easily predicted. An individual can easily change his mind, so his movements are difficult to predict.

In large-scale strategy you can frighten the enemy not by what you present to their eyes, but by shouting, making a small force seem large, or by threatening them from the flank without warning. These things all frighten. You can win by making best use of the enemy's frightened rhythm.
