And there is a saying in the East, "Do not invoke the name of Satan, or he will rise from his grave." An inconsiderate or thoughtless person always falls into the error of wakening this evil, even if it were asleep, for he does not know the music of life. Every person therein is a note, and when one feels this way, then he has before him an instrument. The whole world is an instrument upon which a symphony is to be played.
