Duality, as motor or machine, is a line travelling in both directions. In one we have differentiation – each splitting into two – the explosion of reality into its infinitely dense texture. In the other we have integration – each seeking, proposing, its opposite and then embracing in a figure of eight – unity consuming reality. Our method is relaxation, which in taiji is never a sinking into a low-energy steady state, but rather a means of travelling in both directions at once. In this sense relaxation is simply a physical energetic acceptance of the unthinkableness of reality; and our means of production.
