To Throw into Confusion
This means making the enemy lose resolve.
In large-scale strategy we can use our troops to confuse the enemy on the field. Observing the enemies spirit, we can make them think"Here? There? Like that? Like this? Slow? Fast?"Victory is certain when the enemy is caught up in a rhythm which confuses his spirit.
In single combat, we can confuse the enemy by attacking with varied techniques when the chance arises. Feint a thrust or cut, or make the enemy think you are going to close with him, and when he is confused you can easily win.
This is the essence of fighting, and you must research it deeply.
