The end of all etiquette is to so cultivate your mind that even when you are quietly seared, not the roughest ruffian can dare make onset on your person. It means, in other words, that by constant exercise in correct manners, one brings all the parts and faculties of his body into perfect order and into such harmony with itself and its environment as to express the mastery of spirit over the flesh.
