“A Way consists of principle (ri) and techniques. The principle is formless or abiding in the Tao. Techniques are forms which were once spontaneous expressions of principle by a master. By perfecting form through countless repetitions, a person attains to formlessness. Then a person accords with the myriad changes naturally. Without principle, technique is mechanical; without technique, principle cannot be expressed.”
