Anger. Control your anger. If you hold anger toward others, they have control over you.Your opponent can dominate and defeat you if you allow him to get you irritated.

When the enemy starts to collapse you must pursue him without the chance of letting go. If you fail to take advantage of your enemies collapse, they may recover.

When you attack the enemy, your spirit must go to the extent of pulling the stakes out of a wall and using them as spears and halberds.

If the enemy stays spirited it is difficult to crush him.
