Ultimately, human intentionality is the most powerful evolutionary force on this planet.

It's fitting, then, that we begin this exploration of ourselves and of the world with music, and more specifically with a musical quality called vibrato. This pulsation that wells up within the sounded note can lead us to what is most spontaneous and creative in human life, and possibly even to deeper mysteries--to powers of knowing and doing which we have lost or given away during the epoch of civilization, and which perhaps we may now regain.

What was once impossible now summons us to dismantle the walls between ourselves and our sisters and brothers, to dissolve the distinctions between flesh and spirit, to transcend the present limits of time and matter, to find, at last, not wealth or power but the ecstasy (so long forgotten) of commonplace, unconditional being. For the atom's soul is nothing but energy. Spirit blazes in the dullest of clay. The life of every woman or man-the heart of it-is pure and holy joy.

In terms of the game theory, we might say the universe is so constituted as to maximize play. The best games are not those in which all goes smoothly and steadily toward a certain conclusion, but those in which the outcome is always in doubt. Similarly, the geometry of life is designed to keep us at the point of maximum tension between certainty and uncertainty, order and chaos. Every important call is a close one. We survive and evolve by the skin of our teeth. We really wouldn't want it any other way.

The essence of boredom is to be found in the obsessive search for novelty. Satisfaction lies in mindful repetition, the discovery of endless richness in subtle variations on familiar themes.

At the root of all power and motion, there is music and rhythm, the play of patterned frequencies against the matrix of time, Before we make music, music makes us.

Perhaps we'll never know how far the path can go, how much a human being can truly achieve, until we realize that the ultimate reward is not a gold medal but the path itself.
