Being unconquerable lies with yourself; being conquerable lies with your enemy.

When your opponent gives you an opening, be swift as a hare.

What enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge.

Thus those skilled in war subdue the enemy's army without battle .... They conquer by strategy.

There are not more than five primary colours, yet in combination they produce more hues than can ever been seen.

Therefore the good fighter will be terrible in his onset, and prompt in his decision.

The one who figures on victory at headquarters before even doing battle is the one who has the most strategic factors on his side.
