We practise softness in Taiji in order to develop true hardness – a core of steel. We surrender to gravity↓ to open up to spirit↑. Move slowly to calm monkey mind so that we can fly with lightening speed – quicker than mind. Turn the waist to loosen arms and tighten belly. This is the binary Taoist structure of our work and our world. Not so much yin/yang as Internal/External.
