"Cuando estáis combatiendo contra los enemigos, si tenéis la sensación de estar estancados y de no hacer ningún progreso, abandonad vuestro estado de ánimo y pensad en vuestro corazón que estáis empezando algo nuevo. Cuando conseguís el ritmo, ya sabéis cómo ganar. Esto es "renovarse"."

Many things are said to be passed on. Sleepiness can be passed on, and yawning can be passed on. Time can be passed on also. In large-scale strategy, when the enemy is agitated and shows an inclination to rush, do not mind in the least. Make a show of complete calmness, and the enemy will be taken by this and will become relaxed. When you see that this spirit has been passed on, you can bring about the enemy's defeat by attacking strongly with a Void spirit.

When we are fighting with the enemy, even when it can be seen that we can win on the surface with the benefit of the Way, if his spirit is not extinguished, he may be beaten superficially yet undefeated in spirit deep inside. With this principle of "penetrating the depths" we can destroy the enemy's spirit in its depths, demoralizing him by quickly changing our spirit. This often occurs. Penetrating the depths means penetrating with the long sword, penetrating with the body, and penetrating with the spirit. This cannot be understood in a generalization. Once we have crushed the enemy in the depths, there is no need to remain spirited. But otherwise we must remain spirited. If the enemy remains spirited it is difficult to crush him.
