The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous.

At the heart of it, mastery is practice. Mastery is staying on the path.

For a master, the rewards gained along the way are fine, but they are not the main reason for the journey. Ultimately the master and the master's path are one. And if the traveler is fortunate - that is, if the path is complex and profound enough - the destination is two miles farther away for every mile he or she travels.

The real juice of life, whether it be sweet or bitter, is to be found not nearly so much in the products of our efforts as in the process of living itself, in how it feels to be alive.

Mastery is the art of setting your foot on the path.

To learn is to change.

The subtle dance of the body joins us to the world.
