The military has no constant form, just as water has no constant shape - adapt as you face the enemy, without letting them know beforehand what you are going to do.

Birds rising in flight is a sign that the enemy is lying in ambush; when the wild animals are startled and flee he is trying to take you unaware.

Thus the skilful general conducts his army just as though he were leading a single man, willy-nilly, by the hand.

He who is prudent and lies in wait for an enemy who is not, will be victorious.

Until death itself comes, no calamity need be feared

To know your Enemy, you must become your Enemy.

If you are strong, appear weak. But if you are weak, appear strong.
