Know the enemy and know yourself; in a hundred battles you will never peril.

Unhappy is the fate of one who tries to win his battles and succeed in his attacks without cultivating the spirit of enterprise, for the result is waste of time and general stagnation.

In the midst of difficulties we are always ready to seize an advantage, we may extricate ourselves from misfortune.

Great results, can be achieved with small forces.

A wise general makes a point of foraging of the enemy.

Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected.

Subtle and insubstantial, the expert leaves no trace; divinely mysterious, he is inaudible. Thus he is master of his enemy's fate.
