If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.

Hence the saying: If you know the enemy and you know yourself, your victory will not stand in doubt; if you know Heaven and you know Earth, you may make your victory complete.

To perceive victory when it is known to all is not really skilful. Everyone calls victory in battle good, but it is not really good.

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

So it is said that victory can be made.

The Way of Heaven does not compete, and yet it skillfully achieves victory.
