甲胆乙肝丙小肠，丁心戊胃己脾乡，庚属大肠辛属肺，壬属膀胱癸肾脏，三焦阳府
须归丙，包络从阴丁火旁，阳干为表阴干里，脏腑表里配阴阳。
【按】旧云∶三焦亦向壬中寄，包络同归入癸方。夫三焦为决渎之官，犹可言壬，而
包络附于心主，乌可云癸？况二脏表里，皆相火也，故改正之。
【注】甲、丙、戊、庚、壬阳干也，乙、丁、己、辛、癸阴干也。阳干为表为腑，阴干为里为脏，故
曰∶脏腑表里配阴阳也。
每日寅时从肺起，卯时流入大肠经，辰胃巳脾午心火，未时应注小肠经，申属膀胱
酉属肾，戌走包络亥焦宫，子胆丑肝寅又肺，十二经脉周环行。
【注】人有十二经，昼夜有十二时，每一经主一时。先从寅时入肺起，卯入于大肠，辰
入于胃，巳入于脾，午入于心，未入于小肠申入于膀胱，酉入于肾，戌入于包络，亥入
于三焦，子入于胆，丑入于肝，至于寅时，则又从肺起，此十二经与十二时，相循环而行者也。
肺大胃脾心小肠，膀肾包焦胆肝续，手阴脏手阳手头，足阴足腹阳头足。
【注】人身正脉十有二经，每于平旦寅时，营气始于中焦，上注于手太阴肺经，自胸中
而出于中府，至于少商，以次行于手阳明大肠等十二经，终于足厥阴肝经，而复始于太阴肺经
也。凡手之三阴，从脏走手；手之三阳，从手走头；足之三阴，从足走腹；足之三阳，从头走
足。周流不息，循环无端也。
Gallbladder corresponds to Jia, Liver to Yi, Small Intestine to Bing, Heart to Ding, Stomach to Wu, Spleen to Ji, Large Intestine to Geng, Lung to Xin, Bladder to Ren, Kidney to Gui. The Yang Fu organ of Sanjiao (Triple Burner) must be assigned to Bing, while the Pericardium follows Yin and is associated with Ding Fire. Yang Heavenly Stems represent Exterior and Fu organs, Yin Heavenly Stems represent Interior and Zang organs; thus, the interior-exterior relationships of Zang and Fu organs are matched with Yin and Yang.
[Commentary] Old texts stated: Sanjiao also resides in Ren, and the Pericardium returns to Gui. However, Sanjiao is the official of dredging (responsible for water passages), so it can be said to belong to Ren, but the Pericardium attaches to the Heart Master, how can it be said to belong to Gui? Moreover, the interior-exterior relationship of these two organs both involves Ministerial Fire, hence this correction was made.
[Annotation] Jia, Bing, Wu, Geng, and Ren are Yang Heavenly Stems; Yi, Ding, Ji, Xin, and Gui are Yin Heavenly Stems. Yang stems represent the Exterior and Fu organs, while Yin stems represent the Interior and Zang organs. Therefore, it is said that the interior-exterior pairing of Zang and Fu organs corresponds to Yin and Yang.
At Yin hour daily, circulation begins from the Lung; at Mao hour, it flows into the Large Intestine Meridian. Chen hour belongs to the Stomach, Si hour to the Spleen, Wu hour to Heart Fire, Wei hour should note the Small Intestine Meridian. Shen hour belongs to the Bladder, You hour to the Kidney, Xu hour moves to the Pericardium, Hai hour to the Palace of Sanjiao. Zi hour to Gallbladder, Chou hour to Liver, Yin hour again to Lung; the Twelve Meridians circulate continuously.
[Annotation] Humans have twelve meridians, and there are twelve double-hours in a day and night, each meridian governing one double-hour. It starts first at Yin hour entering the Lung Meridian, Mao hour enters the Large Intestine, Chen hour enters the Stomach, Si hour enters the Spleen, Wu hour enters the Heart, Wei hour enters the Small Intestine, Shen hour enters the Bladder, You hour enters the Kidney, Xu hour enters the Pericardium, Hai hour enters the Sanjiao, Zi hour enters the Gallbladder, Chou hour enters the Liver, and upon reaching Yin hour, it starts again from the Lung. This is the cycle where the twelve meridians and twelve double-hours circulate mutually.
Lung, Large Intestine, Stomach, Spleen, Heart, Small Intestine; Bladder, Kidney, Pericardium, Sanjiao, Gallbladder, Liver follow. Hand Yin connects to Zang organs, Hand Yang connects to the head; Foot Yin connects to the abdomen, Foot Yang connects from head to foot.
[Annotation] The human body has exactly twelve regular meridians. At dawn during the Yin hour, Ying Qi (nutritive qi circulating within the vessels) begins in the Middle Jiao, flows upward into the Hand Taiyin Lung Meridian, exits from the chest at Zhongfu (LU-1), reaches Shaoshang (LU-11), and proceeds sequentially through the Hand Yangming Large Intestine Meridian and the other ten meridians, finally arriving at the Foot Jueyin Liver Meridian, then restarting from the Hand Taiyin Lung Meridian. All three Hand Yin meridians travel from the Zang organs to the hands; all three Hand Yang meridians travel from the hands to the head; all three Foot Yin meridians travel from the feet to the abdomen; all three Foot Yang meridians travel from the head to the feet. They flow endlessly in a continuous, unbroken cycle.
