Siddhartha hatte begonnen, Unzufriedenheit in sich zu nähren. … Er hatte begonnen zu ahnen, daß sein ehrwürdiger Vater und seine anderen Lehrer, daß die weisen Brahmanen ihm von ihrer Weisheit das meiste und beste schon mitgeteilt, daß sie ihre Fülle schon in sein wartendes Gefäß gegossen hätten, und das Gefäß war nicht voll, der Geist war nicht begnügt, die Seele war nicht ruhig, das Herz nicht gestillt.
