Taiji – the Supreme Ultimate – the fundamental Taoist principle of generation and creation – is the separation and interplay of yin and yang. When yin and yang perfectly combine we get emptiness or Wuji. When they cling to each other we get chronic tension: a frozen shoulder, clenched jaw, stagnation, depression, fear – a frozen moment overstaying its welcome. Such conditions we heal with movement: movement of the parts with respect to each other but then also movement within the parts. The latter is more difficult and requires relaxation, energy and imagination.
