The opportunity to secure ourselves against defeat lies in our own hands

Use humility to make the enemy haughty. Tire them by flight. Cause division among them. When they are unprepared, attack and make your move when they do not expect it.

It is according to the shapes that I lay the plans for victory, but the multitude does not comprehend this. Although everyone can see the outward aspects, none understands the way in which I have created victory.

To know your Enemy, you must become your Enemy.

Carefully compare the opposing army with your own, so that you may know where strength is superabundant and where it is deficient.

You can prevent your opponent from defeating you through defense, but you cannot defeat him without taking the offensive.

Invincibility depends on one's self; the enemy's vulnerability on him.
