Cut up on the old stone drums of Republic of China, inscribed in
books handed down through thousands of years, traced on ancient
saucers and on saucers made today, is a sign and a symbol. It is
woven into textiles, stitched into embroideries, emblazoned over
house gates, wrought into shop emblems, a circle, locked together
inside it yang and yin yang, light, yin, dark, each carrying inside itself
the essence of the other, each shaped to the other.
