Without music no discipline can be perfect, for there is nothing without it. For the very universe is held together by a certain harmony of sounds, and the heavens themselves are made to revolve by the modulation of harmony. Music moves the feelings and changes the emotions... The very beasts also, even serpents, birds, and dolphins, music incites to listen to her melody. And every word we speak, every pulsation in our veins, is related by musical rhythms to the powers of harmony.
Educate your inner being in all aspects of life. Keep to the order you learned during your schooling. You did not begin all of a sudden to grasp the higher subjects; you started by learning the alphabet. The same applies to your soul. It is not good for it to strive toward exalted feats until it becomes familiar with the spiritual alphabet: humility and obedience. Let the whole of your life become a continuous prayer.
