If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.
An oak and a reed were arguing about their strength. When a strong wind came up, the reed avoided being uprooted by bending and leaning with the gusts of wind. But the oak stood firm and was torn up by the roots.
The sky is changed,-and such a change! O night And storm and darkness! ye are wondrous strong, Yet lovely in your strength, as is the light Of a dark eye in woman! Far along, From peak to peak, the rattling crags among, Leaps the live thunder.
Say to your own minds, "I am He, I am He". Let it ring day and night in your minds like a song, and at the point of death declare : "I am He". That is truth; the infinite strength of the world is yours.
