I don't want to hear the notes any more, there must be no more notes. Only spirit here!...Abandon yourself to your hearts; it's not enough to interpret the signs you have on the paper in front of your eyes. Look, I'm shuddering here. You must shudder, too... What you're expressing is serenity, contentedness, but it's not joy yet. You have to look for it in yourselves, not in the music.
