Wherefore the good fighter seeks victory from spirit, and does not depend entirely upon the skill of his men. He is careful in his choice, and leaves the rest to battle force; yet, when an opening or advantage shows, he pushes it to its limits.
As a log or rock which, motionless on flat ground, yet moves with ever-increasing force when set on an incline, so await the opportunity, and so act when the opportunity arrives.
If the general be skilful, the spirit of his troops is as the impetus of a round stone rolled from the top of a high mountain.

EMPTINESS AND STRENGTH
Sun the Master said:—
To be the first in the field, and there to await the enemy, is to husband strength.
To be late, and hurrying to advance to meet the foe, is exhausting.
