Is this then one of the practical significances or uses of “the word Om, as expressed in tone?” Does this bell-like resonance have such an effect upon the molecules of the human body, (including those of the brain,) as to polarize them in time to The Spirit? If there are those who doubt the existence of a great undercurrent of universal tone, described by “THE PATH” as Nada Brahma,—“the divine resonance upon which depends the evolution of the visible from the invisible,”—they will at least grant its probability when they consider that this has been admitted by some of the greatest intellects of the world, many of whom firmly believed in the “music of the spheres.” Plato taught it. Maximus Tyrius says that “the mere proper motion of the planets must create sounds, and as the planets move at regular intervals, these sounds must be harmonious.” The Cyclopœdia Britanica says, “the origin of musical sounds consists in the regular, periodic vibration of some surface in contact with the air, whereby motion is imparted to the air. The loudness or intensity of the note depends on the magnitude of the motion or pitch.” The regular motions of the planets of our system, as well as those of known moving stars, such as Sirius, may well be accompanied by a rythmical sound arising from the ether waves thus set in motion. That we do not hear it, may be due to the density of our atmosphere, yet it may be none the less transmitted along the ether waves and heard by the inner ear of those whose sense is developed. Pythagoras was the first philosopher to suggest this idea, which is mentioned by Shakespear: “There’s not the smallest orb which thou behold’st But his motion like an angel sings, Still quiring to the young eyed cherubims: _Such harmony is in immortal souls_; But while this muddy vesture of decay Doth grossly close it in, we cannot hear it.” He also speaks of it again in Pericles. “Keppler’s idea of the universe was essentially Pythagorean and Platonic. He thought that the planetary movements were related to musical intervals.” (Cyclo. Brit.) Montaigne, Milton, Donne, Pope, Newton, Tycho-Brahe and others believed in the “music of the spheres.” Faber beautifully attributed it to the vibration caused by the shooting rays of light on their journey earthward: “Thou art fugitive splendors made vocal As they glanced from that shining sea.” All are agreed that the idea has come down to us from the earliest times.
