（灵枢九针十二原篇）
五脏有六腑，六腑有十二原，十二原出于四关。四关主治五脏，五脏有疾，当取之十二原。（脏腑之气，表里相通，
故五脏之表有六腑，六腑之外有十二原，十二原出于四关。四关者，即两肘两膝，乃周身骨节之大关也。故凡井荥 原
经合穴，皆手不过肘，足不过膝。而此十二原者，故可以治五脏之疾。）十二原者，五脏之所以禀三百六十五节气味也。
五脏有疾也，应出十二原，十二原各有所出。明知其原，睹其应，而知五脏之害矣。（此十二原者，乃五脏之气所注，三
百六十五节气味之所出也。故五脏有疾者，其气必应于十二原而各有所出。知其原，睹其应，则可知五脏之疾为害矣。）
阳中之少阴，肺也，其原出于大渊，大渊二。（心肺居于膈上，皆为阳脏，而肺则阳中之阴，故曰少阴。其原出于大渊二
穴，即寸口也。）阳中之太阳，心也，其原出于大陵，大陵二。（心为阳中之阳，故曰太阳。其原出于大陵，按大陵系手
厥阴心主 穴也。邪客篇∶帝曰∶手少阴之脉独无 何也？岐伯曰∶少阴，心脉也。心者，五脏六腑之大主也，精神之
所舍也，其脏坚固，邪弗能容也。容之则心伤，心伤则神去，神去则死矣。故诸邪之在于心者，皆在于心之包络，包络
者心主之脉。故此言大陵也。大陵二穴，在掌后骨下两筋间。）阴中之少阳，肝也，其原出于太冲，太冲二。（肝脾肾居
于膈下，皆为阴脏，而肝则阴中之阳，故曰少阳。其原出于太冲二穴，在足大趾本节后二寸，动脉陷中。）阴中之至阴，
脾也，其原出于太白，太白二。（脾属土而象地，故为阴中之至阴。其原出于太白二穴，在足大趾后内侧核骨下陷中。）
阴中之太阴，肾也，其原出于太溪，太溪二。（肾在下而属水，故为阴中之太阴。其原出于太溪二穴，在足内踝后跟骨上
动脉陷中。此上五脏阴阳详义，又见阴阳类五。）膏之原，出于鸠尾，鸠尾一。（鸠尾，任脉穴，在臆前蔽骨下五分。）盲
之原，出于脖 ，脖 一。（脖 ，即下气海，一名下肓，在脐下一寸半，任脉穴。脖音孛。 音英。）凡此十二原者，
主治五脏六腑之有疾者也。（上文五脏之原各二，并膏盲之原，共为十二，而脏腑表里之气皆通于此，故可以治五脏六腑
之有疾者也。）
The chapter "Nine Needles and Twelve Yuan Source Points" from the *Ling Shu* (Spiritual Pivot) states: The five Zang organs are paired with the six Fu organs; beyond the six Fu organs, there are twelve Yuan Source points. These twelve Yuan Source points derive their Qi from the "Four Passes." The Four Passes govern the diseases of the five Zang organs; when the five Zang organs are afflicted, one should select these twelve Yuan Source points for treatment. (The Qi of the Zang and Fu organs communicates internally and externally; thus, the exterior of the five Zang organs connects to the six Fu organs, and beyond the six Fu organs lie the twelve Yuan Source points, which originate from the Four Passes. The "Four Passes" refer to the two elbows and two knees, which are the major joints of the body. Therefore, regarding the Jing-River-Stream-Well-He Five Shu points, those on the upper limbs do not extend beyond the elbows, and those on the lower limbs do not extend beyond the knees. However, these twelve Yuan Source points can therefore treat diseases of the five Zang organs.) The twelve Yuan Source points are where the five Zang organs receive the Qi and flavors of the three hundred and sixty-five seasonal influences. When the five Zang organs have disease, the pathological Qi manifests at the twelve Yuan Source points, each having its specific location. By clearly knowing the Yuan Source points and observing their responses, one can understand the harm caused by diseases of the five Zang organs. (These twelve Yuan Source points are where the Qi of the five Zang organs gathers and where the Qi and flavors of the three hundred and sixty-five seasonal influences emerge. Thus, when the five Zang organs are diseased, their Qi must respond at the twelve Yuan Source points with specific manifestations. Knowing the Yuan Source points and observing their responses allows one to discern the harm of diseases in the five Zang organs.)
The organ belonging to Yang within Yin (Shao Yin) is the Lung (Fei), whose Yuan Source point is Taiyuan (LU-9), bilateral, two points. (The Heart and Lung reside above the diaphragm and are both considered Yang organs, but the Lung is Yin within Yang, hence termed Shao Yin. Its Yuan Source point emerges from the two Taiyuan points, which correspond to the Cun Kou pulse position.) The organ belonging to Yang within Yang (Tai Yang) is the Heart (Xin), whose Yuan Source point is Daling (PC-7), bilateral, two points. (The Heart is Yang within Yang, hence termed Tai Yang. Its Yuan Source point emerges from Daling. Note that Daling belongs to the Pericardium Meridian of Hand-Jueyin. In the chapter "Evil Invaders," it is recorded: The Yellow Emperor asked, "Why does the Hand-Shaoyin meridian alone lack acupoints?" Qibo replied, "Shaoyin refers to the Heart meridian. The Heart is the great master of the five Zang and six Fu organs and the residence of the Spirit. Its substance is solid, and evil cannot invade it. If evil invades, the Heart is damaged; if the Heart is damaged, the Spirit departs; if the Spirit departs, death occurs. Therefore, any evil affecting the Heart actually affects the Pericardium (Bao Luo), which is the meridian of the Heart Master. Hence, this text refers to Daling." The two Daling points are located in the depression between the two tendons below the wrist crease.) The organ belonging to Yin within Yang (Shao Yang) is the Liver (Gan), whose Yuan Source point is Taichong (LR-3), bilateral, two points. (The Liver, Spleen, and Kidney reside below the diaphragm and are all considered Yin organs, but the Liver is Yang within Yin, hence termed Shao Yang. Its Yuan Source point emerges from the two Taichong points, located two cun posterior to the root of the big toe, in the depression where the artery beats.) The organ belonging to Yin as Supreme Yin (Zhi Yin) is the Spleen (Pi), whose Yuan Source point is Taibai (SP-3), bilateral, two points. (The Spleen belongs to Earth and symbolizes the ground, hence termed Supreme Yin within Yin. Its Yuan Source point emerges from the two Taibai points, located in the depression behind and medial to the sesamoid bone of the big toe.) The organ belonging to Yin as Great Yin (Tai Yin) is the Kidney (Shen), whose Yuan Source point is Taixi (KI-3), bilateral, two points. (The Kidney is located inferiorly and belongs to Water, hence termed Great Yin within Yin. Its Yuan Source point emerges from the two Taixi points, located in the depression behind the medial malleolus where the artery beats. The detailed meanings of Yin and Yang of the five Zang organs mentioned above are also found in the chapter "Yin Yang Categories V.") The Yuan Source point of the Gao (fatty tissue) is Jiawei (CV-15), single point, one. (Jiawei is a Ren Mai point, located five fen below the xiphoid process.) The Yuan Source point of the Huang (membranous tissue) is Boying (CV-12), single point, one. (Boying is also known as Xia Qihai or Xia Huang, located one and a half cun below the umbilicus, and is a Ren Mai point. "Bo" sounds like "Bei"; "Ying" sounds like "Ying".) All these twelve Yuan Source points govern the diseases of the five Zang and six Fu organs. (The Yuan Source points of the five Zang organs mentioned above are two each, plus the Yuan Source points of Gao and Huang, totaling twelve. Since the Qi of the interior and exterior of the Zang and Fu organs all connect here, they can treat diseases of the five Zang and six Fu organs.)
