The T'ai Chi principles are even more important than the movements for they are the laws of nature that shape us every moment. Moving in slow motion while listening internally promotes calmness and sensitivity to the eternal laws and rhythms of our universe. Relaxation is the first and foremost principle. Not at all weak or limp nor tight and stiff, this is an alert, vibrant condition that promotes fluid gracefulness while enhancing sensitivity, a prime requirement in our world of constant change. T'ai Chi coaxes the body into loosening and opening so that internal energy may flow freely.
Blood circulation is enhanced as the capillaries open, for example.
Regular practice with mental concentration provides early recognition and amelioration of physical and mental tension. Verticality of the spine is another important principle. Leaning even slightly in any direction means tensing the body in a losing battle with gravity. The top of the head is kept horizontal and the spine upright and open so the muscles along the spine may relax. The spine is a major energy path that deserves close attention.
