Silence is the property, the contemplative quality, the fruit of faith. Interior, mystical silence is a silence which stems from the intensity of loving faith ... the interior result of a heart that loves intensely. The presence in our hearts of a secret to be kept brings about a density which is interior silence. Communication of secrets is the sign which manifests and proves the friendship and total trust of a friend.
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.
