“Polish your wisdom: learn public justice, distinguish between good and evil, study the ways of different arts one by one.”

“There is no one way to salvation, whatever the manner in which a man may proceed. All forms and variations are governed by the eternal intelligence of the Universe that enables a man to approach perfection. It may be in the arts of music and painting or it may be in commerce, law, or medicine. It may be in the study of war or the study of peace. Each is as important as any other. Spiritual enlightenment through religious meditation such as Zen or in any other way is as viable and functional as any "Way."... A person should study as they see fit.”

“The true science of martial arts means practicing them in such a way that they will be useful at any time, and to teach them in such a way that they will be useful in all things.”

“Do not sleep under a roof. Carry no money or food. Go alone to places frightening to the common brand of men. Become a criminal of purpose. Be put in jail, and extricate yourself by your own wisdom.”

“Become acquainted with every art.”
