天有十干，地支十二。以干加支，常遗其二。二一合化，五运六气，是以甲、乙、丙、
丁、
死，所以甲犹草木，原因壬癸。气行于天，质具于地。质气之分阴质、阳气，故阳主变化，
阴主专静，而莫自制。是以阳府示原，阴藏隐秘。然夫自子至巳，六阳化合；自午至亥，六
阴变化。惟壬得一，癸二从之，为阴阳动静之枢纽，气数欲兆之时。故气运一周，一会于壬
癸，交接挥持，莫为其纪，故子午流注真诀，甲始于戌而壬亥为终，壬子、癸丑为终始之地
。一顺一逆，一纵一横，一起一止，一变一互，一合一化，一君一臣，一佐一使，一生一克
，一母一子，一夫一妇，交神合气，变化无穷。所以一岁总六十穴，月、日、时，刻，一刻
备六十穴，岁明，月、日如之，其何以然哉！日、月，三十日则一会于壬，河图一穴居北而
括万极，此皇极先天之数所由起，五行五气，所由化合，子午流注针法之心要也，神之变化
甲胆乙肝丙小肠，丁心戊胃己脾乡，
庚是大肠辛是肺，壬属膀胱癸肾详。
十二经行十二时，子原是胆丑肝之，
肺居寅位大肠卯，辰胃流传巳在脾，
午字便随心脏定，未支须向小肠宜，
申膀酉肾戌包络，惟有三焦亥上推。
手之三阴∶肺，太阴；心，少阴；心包，厥阴。
足之三阴∶脾，太阴；肾，少阴；肝，厥阴。
手之三阳∶小肠，太阳；三焦，少阳；大肠，阳明。
足之三阳∶膀胱，太阳；胆，少阳；胃，阳明。
天有十个天干，地支有十二个。将天干加在地支上，总会剩下两个。这两个剩下的干支相合而化生，构成了五运六气的基础。因此，甲、乙属木，丙、丁属火，戊、己属土，庚、辛属金，壬、癸属水。因为甲如同草木初生，根源在于壬、癸之水。气运行于天，质构成于地。质与气的区分中，阴质主静，阳气主动，所以阳主变化，阴主专静，二者相互制约而无法自我主宰。因此，阳腑显示本源，阴藏则隐秘深奥。然而从子时到巳时，是六个阳时的化合；从午时到亥时，是六个阴时的变化。只有壬得到一，癸得到二并顺从它，这是阴阳动静的枢纽，也是气数将要显现的时候。所以气运循环一周，会在壬、癸交会，交接维持，没有固定的纪年标准，因此子午流注（一种根据时辰推算气血流注的针灸方法）的真诀是：甲始于戌时，而壬在亥时结束，壬在子时、癸在丑时是终始之地。一顺一逆，一纵一横，一起一止，一变一互，一合一化，一君一臣，一佐一使，一生一克，一母一子，一夫一妇，交神合气，变化无穷。所以一年总共六十穴，月、日、时、刻，一刻备齐六十穴，岁明，月、日也是如此，这为什么呢？日、月，三十日则一会于壬，河图（中国古代关于数学和宇宙结构的理论图示）中一穴居北而括万极，这是皇极先天之数由此产生的原因，五行五气由此化合，这也是子午流注针法的心要，神的变化的体现。
甲对应胆，乙肝对应小肠，丙对应心，丁对应胃，戊对应脾，己对应脾乡（此处原文可能有误或特指，通常己为脾，庚为大肠，辛为肺，壬为膀胱，癸为肾），庚是大肠，辛是肺，壬属膀胱，癸肾详（详细对应）。
十二经脉运行于十二个时辰，子时原是胆经，丑时是肝经，寅位是肺经，卯时是大肠经，辰时胃经流传，巳时在脾经，午字便随心脏定，未时须向小肠宜，申时膀胱，酉时肾，戌时包络（心包络），惟有三焦经在亥时上推。
手部的三条阴经：肺经，属于太阴；心经，属于少阴；心包经，属于厥阴。
足部的三条阴经：脾经，属于太阴；肾经，属于少阴；肝经，属于厥阴。
手部的三条阳经：小肠经，属于太阳；三焦经，属于少阳；大肠经，属于阳明。
足部的三条阳经：膀胱经，属于太阳；胆经，属于少阳；胃经，属于阳明。
The Heaven has ten Heavenly Stems, and the Earth has twelve Earthly Branches. When adding the Stems to the Branches, two are always left over. These two combine and transform, forming the basis of the Five Movements and Six Qi (Wu Yun Liu Qi, a traditional Chinese medical theory regarding climatic cycles). Therefore, Jia and Yi belong to Wood, Bing and Ding belong to Fire, Wu and Ji belong to Earth, Geng and Xin belong to Metal, Ren and Gui belong to Water. Because Jia is like the sprouting of grass and trees, its root lies in the water of Ren and Gui. Qi moves in the Heaven, while substance constitutes the Earth. In the distinction between substance and Qi, Yin substance is quiet, and Yang Qi is active; thus, Yang governs transformation, and Yin governs stillness, yet they cannot self-regulate. Therefore, Yang Fu organs reveal their origins, while Yin Zang organs remain hidden. However, from Zi hour to Si hour, there is the combination of six Yang hours; from Wu hour to Hai hour, there is the transformation of six Yin hours. Only Ren obtains one, and Gui obtains two and follows it, serving as the pivot of Yin-Yang movement and stillness, the time when Qi numbers are about to manifest. Thus, when Qi completes a cycle, it meets at Ren and Gui, exchanging and maintaining without a fixed chronological standard. Hence, the true secret of Zi Wu Liu Zhu (a acupuncture method calculating Qi flow according to time) states that Jia begins at Xu hour, and Ren ends at Hai hour, with Ren at Zi hour and Gui at Chou hour being the places of beginning and end. One forward, one backward; one vertical, one horizontal; one rising, one stopping; one transforming, one interchanging; one combining, one changing; one ruler, one minister; one assistant, one envoy; one generating, one overcoming; one mother, one child; one husband, one wife; interacting spirits and merging Qi, with infinite transformations. Therefore, there are sixty acupoints in total for a year. For months, days, hours, and quarters, each quarter contains sixty acupoints. The year is clear, and so are the months and days. Why is this? For the Sun and Moon, every thirty days meets at Ren. In the He Tu (River Map, an ancient Chinese diagram representing mathematical and cosmological principles), the point 'one' resides in the North and encompasses all extremes. This is how the number of Huangji Xiantian (Supreme Ultimate Pre-Heaven) originates, and how the Five Elements and Five Qi combine and transform. This is the heart's essence of the Zi Wu Liu Zhu acupuncture method, the manifestation of divine change.
Jia corresponds to Gallbladder, Yi to Liver, Bing to Small Intestine, Ding to Heart, Wu to Stomach, Ji to Spleen, Geng to Large Intestine, Xin to Lung, Ren to Bladder, Gui to Kidney.
The Twelve Meridians circulate through the Twelve Hours: Zi belongs to Gallbladder, Chou to Liver, Yin to Lung, Mao to Large Intestine, Chen to Stomach, Si to Spleen, Wu to Heart, Wei to Small Intestine, Shen to Bladder, You to Kidney, Xu to Pericardium, and only San Jiao (Triple Burner) is pushed to Hai.
Three Yin Meridians of the Hand: Lung Meridian, Taiyin (Greater Yin); Heart Meridian, Shaoyin (Lesser Yin); Pericardium Meridian, Jueyin (Terminal Yin).
Three Yin Meridians of the Foot: Spleen Meridian, Taiyin (Greater Yin); Kidney Meridian, Shaoyin (Lesser Yin); Liver Meridian, Jueyin (Terminal Yin).
Three Yang Meridians of the Hand: Small Intestine Meridian, Taiyang (Greater Yang); San Jiao Meridian, Shaoyang (Lesser Yang); Large Intestine Meridian, Yangming (Bright Yang).
Three Yang Meridians of the Foot: Bladder Meridian, Taiyang (Greater Yang); Gallbladder Meridian, Shaoyang (Lesser Yang); Stomach Meridian, Yangming (Bright Yang).
