Circles, circles, everywhere – set up by turning, always turning. Sinking in taiji is a sinking into circularity – falling, or rather being sucked, into a maelstrom, or rather two maelstroms, each rising up through the body from a foot like spinning funnels, channeling energy both down and up. Such energetic structures only reveal themselves when the Form is practised quickly. The Form is a celebration of movement, above all, turning, and if practised as such then the shapes the body takes as it turns are a consequence of that turning: of centrifugal and centripetal forces, and as soon as movement stops and those forces dissipate, then the body collapses. This is our path to lightness.
