of the Six Pitch-pipes [六律] and the Five Elements [五行氣]. Therefore, he has in [his body] the Five Reservoirs [五藏] and the Six Storehouses [六府], through which the Instincts and Emotions go in and out." (tr. Tjan 1952: 566). Six dynasties The historical term "Six Dynasties" collectively refers to the Three Kingdoms (220–280 CE), Jin Dynasty (265–420), and Southern and Northern Dynasties (420–589). The c. 3rd-4th century Huangting jing (黃庭經, "Scripture of the Yellow Court") contrasts the respiration of ordinary people and Daoists inhaling through the nose and exhaling through the mouth. Ordinary people's breath supposedly descends from the nose to the kidneys, traverses the Five Viscera (kidneys, heart, liver, spleen, and lungs), then the Six Receptacles (gall bladder, stomach, large intestine, small intestine, triple burner, and bladder), where it is blocked by the "Origin of the Barrier, [guanyuan 關元, the Bl-26 acupuncture point], the double door of which is closed with a key and guarded by the gods of the spleen, both clad in red," whereupon the breath rises to the mouth and is exhaled (Maspero 1981: 341). Daoist adepts knew how to control their breath to open these doors and lead it to the Lower Cinnabar Field or Ocean of Breath [qihai 氣海], three inches below the navel. Then is the moment of "leading the breath", [xingqi], in such a way that "the breaths of the Nine Heavens (= the inhaled air), which have entered the man's nose, make the tour of the body and are poured into the Palace of the Brain". The "breath is led" by Interior Vision, [neiguan], thanks to which the Adept sees the inside of his own body and, concentrating his thought, steers the breath and guides it, following it by sight through all the veins and passages of the body. Thus it is led where one wishes. If one is sick (that is, if some passage inside the body is obstructed and hampers the regular passage of air), that is where one leads it to reestablish circulation, which produces healing. The adept then circulates the Ocean of Breath to ascend the spinal column into the Upper Cinnabar Field (brain), go back down to the Middle Cinnabar Field (heart), when it is expelled by the lungs and goes out through the mouth. (Maspero 1981: 342). The Jin dynasty Daoist scholar Ge Hong's 318 Baopuzi ("Master Who Embraces Simplicity") frequently mentions xingqi; written (行氣,
