Miyamoto Musashi - Go Rin No Sho: A Book Of Five Rings (To Crush) lyrics

This means to crush the enemy regarding him as being weak. In large−scale strategy, when we see that the enemy has few men, or if he has many men but his spirit is weak and disordered, we knock the hat over his eyes, crushing him utterly. If we crush lightly, he may recover. You must learn the spirit of crushing as if with a hand−grip. In single combat, if the enemy is less sk**ful than ourselves, if his rhythm is disorganized, or if he has fallen into evasive or retreating attitudes, we must crush him straightaway, with no concern for his presence and without allowing him space for breath. It is essential to crush him all at once. The primary thing is not to let him recover his position even a little. You must research this deeply.
