The Union of Heaven and Earth
“The round shape of our head emulates heaven. The square shape of our feet emulates earth. Heaven has the four seasons, the five movements, the nine divisions, and the 366 days. Human beings have four limbs, five organ (zhang) systems, nine orifices, and 366 joints. Heaven has wind, rain, cold, and (summer) heat, while human temperament has ‘taking’, ‘giving’, joy, and anger. Our gallbladder functions like clouds, the lung like mist, the liver like wind, the kidney like rain, and the spleen like thunder. All of these are the union of Heaven and Earth made manifest within the human being.” ~ The Huainan Masters (Huainanzi): JingShen Xun, 120 B.C.E..
