From the recording Three in One and One in Three

Lyrics

Study carefully (x3) Extending and contracting, Opening and closing, Are they natural (x2). To enter my door and be shown the way, Have you been taught? Perfecting skill by practice. Developing technique by study. Let's talk about the body, and its function, Who sets the standard? Who sets the standard? My bones and muscles are my kingdom, But my mind and breath are my glory, Are my glory. Study carefully.
(from "The Essence Of Tai Chi Chuan"-traditional)
