Donald A. Mackenzie, Myths of China and Japan (1923)
“ Yin is “the principle of darkness, cold, and death, standing in the universe diametrically opposite to Yang”.46 The chief source of Yang is the sun, which gives forth “shen” or “soul substance”; the chief source of Yin is the moon. Yang strengthens the vital energy, and is the active principle in various elixirs of life, including, as De Groot notes, “the cock, jade, gold, pearls, and the products of pine and cypress trees”.47 Yin and Yang are controlled by the constellation, the Great Bear, called in China “the Bushel”. ”
