In strategy your spiritual bearing must not be any different from normal. Both in fighting and in everyday life you should be determined though calm. Meet the situation without tenseness yet not recklessly, your spirit settled yet unbiased.
Miyamoto MusashiDo 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 Musashi
