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.

In war, numbers alone confer no advantage. Do not advance relying on sheer military power.

Attack where he is unprepared; sally forth when he does not expect you.

Do not engage an enemy more powerful than you. And if it is unavoidable and you do have to engage, then make sure you engage it on your terms, not on your enemy's terms.

As water shapes its flow in accordance with the ground, so an army manages its victory in accordance with the situation of the enemy.

If the mind is willing, the flesh could go on and on without many things.

If it is to your advantage, make a forward move; if not, stay where you are.

Victory is the main object in war.

Do not press an enemy at bay.
