I experience the Divine Presence in many ways, but the form most often available to me is "spiration," or the act of breathing in which the Spirit often manifests itself and communicates itself. This process has given rise to the experience of inspiration, or in-spiration, in which the Spirit breathes into us. To be aware of God through spiration is to become conscious of God's subtle Presence through our own breathing.
We all share in the eternal spiration of the Spirit. When I am sufficiently absorbed in the experience of divine spiration, I realize inwardly my dependence, and that of all beings, on this subtle action of the Source.
To realize that we are one with the Creator, as Beethoven did, is a wonderful and awe-inspiring experience. Very few human beings ever come into that realization and that is why there are so few great composers or creative geniuses in any line of human endeavor. I always contemplate all this before commencing to compose... Spirit is the creative energy of the Cosmos. Our soul is not conscious of its power until it is enlightened by the Spirit. Therefore, to evolve and grow, we must learn how to use and develop our own soul forces... The real genius draws on the Infinite Source of Wisdom and Power.
