In large-scale strategy it is important to cause loss of balance. Attack without warning where the enemy is not expecting it, and while his spirit is undecided follow up your advantage and, having the lead, defeat him.

Or, in single combat, start by making a show of being slow, then suddenly attack strongly. Without allowing him space for breath to recover form the fluctuation of spirit, you must grasp the opportunity to win. Get the feel of this.

To Frighten

Fright often occurs, caused by the unexpected.

In large-scale strategy you can frighten the enemy not just by what you present to their eyes, but by shouting, making a small force seem large, or by threatening them from the flank without warning. These things all frighten. You can win by making best use of the enemy's frightened rhythm.

In single combat, also, you must use the advantage of taking the enemy unawares by frightening him with your body, long sword, or voice, to defeat him. You should research this well.

To Soak In

When you have come to grips and are striving together with the enemy, and you realise that you cannot advance, you "soak in" and become one with the enemy. You can win by applying a suitable technique while you are mutually entangled.

In battles involving large numbers as well as in fights with small numbers, you can often win decisively with the advantage of knowing how to "soak" into the enemy, whereas, were you to draw apart, you would lose the chance to win. Research this well.

To Injure the Corners

It is difficult to move strong things by pushing directly, so you should "injure the corners".

In large-scale strategy, it is beneficial to strike at the corners of the enemy's force. If the corners are overthrown, the spirit of the whole body will be overthrown. To defeat the enemy you must follow up the attack when the corners have fallen.
