Rumi said that all words are fingers pointing to the moon, and we think the words are the moon. But because of the light, the light of love, the energy and motion that have called us to prayer, bits of this deeper reality are perceivable, and little bits of it will have to do.
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.
