“Pranava,* the sound of the creative Aum vibration, is the mother of all sounds. The intelligent cosmic energy of Aum that issues forth from God, and is the manifestation of God, is the creator and substance of all matter. This holy vibration is the link between matter and Spirit. Meditation on Aum is the way to realize the true Spirit-essence of all creation. By inwardly following the sound of Pranava to its source, the yogi's consciousness is carried aloft to God.” [Paramahansa Yogananda]
- Pranava: literally "that which is sounded out loudly"; something that pervades life, or runs through prana or breath; the primal sound vibration.
