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.
The acquirement of spiritual wisdom does not necessarily prevent us from making worldly mistakes; but because it develops the qualities that will prevent them, and because it takes to heart the lessons of experience, humbly and receptively, it does reduce the frequency of those mistakes.
