The term Meikyo Shisui is a four letter idiom of Japanese Chinese syncretic philosophy combining the wisdom of Sun Tsu, being that of the "clear mirror", and the wisdom of Confucius, being that of the "still water", in that both are capable of reflecting the truth. It is followed as a trained state of mind not unlike the concept of Mushin, in that being calm and steady to return to one's undisturbed state in the face of adversity or activity, one is capable of properly grasping the situation at hand and learning of its properties undisturbed, to follow through without fault and with understanding of what path of action to take.
