Do not let your spirit be influenced by your body, or your body be influenced by your spirit. Be neither insufficiently spirited or over spirited. An elevated spirit is weak and a low spirit is weak. Do not let the enemy see your spirit.
Miyamoto MusashiTo cut and slash are two different things. Cutting, whatever form of cutting it is, is decisive, with a resolute spirit. Slashing is nothing more than touching the enemy.
