The enlightened ruler is heedful, and the good general full of caution.

Those who do not know the plans of competitors cannot prepare alliances. Those who do not know the lay of the land cannot maneuver their forces. Those who do not use local guides cannot take advantage of the ground.

The one who figures on victory at headquarters before even doing battle is the one who has the most strategic factors on his side.

Subjugating the enemy's army without fighting is the true pinnacle of excellence.

There are not more than five musical notes, yet the combinations of these five give rise to more melodies than can ever be heard.There are not more than five primary colors, yet in combination they produce more hues than can ever been seen.There are not more than five cardinal tastes, yet combinations of them yield more flavors than can ever be tasted.

So in war, the way is to avoid what is strong and to strike at what is weak. Water shapes its course according to the nature of the ground over which it flows; the soldier works out his victory in relation to the foe whom he is facing.

Great results, can be achieved with small forces.
