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.

Keep practicing, even when you seem to be getting nowhere.

History tells us more than we want to know about what is wrong with man, and we can hardly turn a page in the daily press without learning the specific time, place, and name of evil. But perhaps the most pervasive evil of all rarely appears in the news. This evil, the waste of human potential, is particularly painful to recognize for it strikes our parents and children, our friends and brothers, ourselves.

If you intend to take the journey of mastery, the best thing you can do is to arrange for first-rate instruction.

There is a human striving for self-transcendence. It's part of what makes us human. With all of our flaws we want to go a little bit further than we've gone before and maybe even further than anyone else has gone before.

Practice is the path of mastery.

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.
