Book excerpt: Universal Consciousness is A–U–M or Pranavam, i.e., Spirit–Breath–Sound–Life. Spirit or Eternal Breath is Motion, and motion animates matter. Eternal Motion is Svara or Vibration, the substratum of the Pythagorean Music of the Spheres. And thus by endless combinations, modifications, and individualisations of the Seven Tattvas or Forces of Nature, which in turn produce every sound, form, and colour, the Divine Mind exhibits periodically aspects of itself to the perception of finite minds. There can be no sound without vibration, for the former is the consequence of the latter. Vibration is caused by the difference in the density of material particles, the solid being moved by the liquid, and the liquid by the gaseous. Divine spirit animates inert mass. Air, breath, life, sound, and form are interconnected. Cosmic mind is the prime mover of everything in the manifested universe. Physical forces are only secondary effects, guided by spiritual forces. Colours of the human voice. Colours of musical instruments. Colours of languages. Table of Tattvas showing their sounds, forms, and colours. The four states of matter correspond to the four states of consciousness.
