One mark of a great soldier is that he fight on his own terms or fights not at all.

If the enemy opens the door, you must race in.

One who speaks deferentially but increases his preparations will advance. One who speaks belligerently and advances hastily will retreat.

When he utilizes combined energy, his fighting men become, as it were, like rolling logs or stones... The energy developed by good fighting men is as the momentum of a round stone rolled down a mountain thousands of feet in height.

All wars are won or lost before they are ever fought.

The line between disorder and order lies in logistics.

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