In Taiji we engage & work with the two natural forces of gravity & levity. Gravity pulls the body down onto (and eventually into) the Earth. Levity lifts the spirit up to (and eventually into) the firmament – the expanse of an ever-expanding universe. The natural function of the mind is to equilibrate these two forces rather than think to itself. When I think to myself then gravity overpowers levity and I need to right the balance by waking up & letting my spirit soar. All of our problems, as individuals & as social members, stem from the incorrect use of the mind, from idle thought.
