Creation begins with the activity of consciousness, which may be called vibration, and every vibration starting from its original source is the same, differing only in its tone and rhythm caused by a greater or lesser degree of force behind it. On the plane of sound, vibration causes diversity of tone, and in the world of atoms, diversity of color. It is by massing together that the vibrations become audible, but at each step towards the surface they multiply and, as they advance, they materialize.
