There is a saying in the East, "Do not invoke the name of Satan or he will rise from his grave." An inconsiderate or tactless person always falls into the error of awakening this evil even if it is asleep, for he does not know the music of life. In order to live in the world one should become a musician of life. Every person therein is a note, and the one who feels this way has an instrument before him: the whole world is an instrument upon which a symphony is to be played.
