The Confucian scholar in the late Edo period says that you never make mistakes if you think, judge cooly with your heart in the right place and open, and remain placid with nerves of steel. Being the same as a memory method of relating things that should be remembered to familiar things one by one, knowledge may also be useful as an immediate self-discipline of mind if you relate it to parts of the body. From analects, "Genshi Shiroku" (fully translated and annotated by Masamitsu Kawakami).
