黄帝曰∶余闻九候于夫子。众多博大。不可胜数。余愿闻要道。以属子孙。传之后世。
着之骨髓。藏之肝肺。歃血而受。不敢妄泄。令合天道。必有终始。上应天光星辰历纪。下
副四时五行贵贱。更立冬阴夏阳。以人应之奈何。愿闻其方。岐伯曰∶妙乎哉问也。此天地
之至数。帝曰∶愿闻天地之至数。岐伯曰∶始于一终于九焉。一者天。二者地。三者人。因
而三之。三三者九。以应九野。故人有三部。部有三候。以决死生。以处百病。以调虚实。
而除邪疾。帝曰∶何谓三部？岐伯曰∶有下部。有中部。有上部。部各有三候。三候者。有
天有地有人也。必指而导之。乃以为真。故下部之天以候肝。地以候肾。人以候脾胃之气。
帝曰∶中部之候奈何？岐伯曰∶亦有天。亦有地。亦有人。天以候肺。地以候胸中之气。人
以候心。帝曰∶上部以何候之？岐伯曰∶亦有天。亦有地。亦有人。天以候头角之气。人以

黄帝说：我从老师那里听说了九候诊法。内容众多且广博，无法一一列举。我希望听取其中的关键道理，以便传授给子孙后代，流传于后世。将其铭记在心（着之骨髓），深藏于内（藏之肝肺），歃血为誓接受教诲，不敢随意泄露。使其符合天道规律，必定有始有终，上应天光星辰的历法纪年，下合四季五行的贵贱变化，冬阴夏阳交替更迭。如何以人体来对应这些规律呢？希望听听具体的方法。
岐伯说：问得真妙啊！这是天地间的至高法则。
黄帝说：希望听听天地间的至高法则。
岐伯说：起始于一，终结于九。一代表天，二代表地，三代表人。在此基础上再乘以三，三三得九，以对应九州（九野）。所以人体分为三部，每部有三候，用以判断生死，诊治百病，调节虚实，祛除邪气疾病。
黄帝说：什么叫三部？
岐伯说：有下部、中部、上部。每部各有三候。这三候分别对应天、地、人。必须通过指切脉象并加以引导观察，才能掌握其真谛。所以下部的“天”候用来诊察肝脏，“地”候用来诊察肾脏，“人”候用来诊察脾胃之气。
黄帝说：中部的脉候是怎样的？
岐伯说：也有天、地、人。天的脉候用来诊察肺脏，地的脉候用来诊察胸中之气，人的脉候用来诊察心脏。
黄帝说：上部用什么来诊察？
岐伯说：也有天、地、人。天的脉候用来诊察头角之气，人的脉候用来诊察耳目之气，地的脉候用来诊察口齿之气。
这三部各有天、地、人。三个三构成天，三个三构成地，三个三构成人。合起来就是九，九分为九野，九野对应九脏。所以神脏有五，形脏有四，合起来共九脏。如果五脏精气败坏，面色必然枯槁无华，面色枯槁无华则必死无疑。
黄帝说：如何根据脉象来判断病情？
岐伯说：必须先度量患者体形的肥瘦，以调察其气的虚实。实证用泻法，虚证用补法。必须先疏通血脉，然后再进行调理。无论什么疾病，都以达到平衡为最终目的。
黄帝说：如何判断生死？
岐伯说：形体壮盛但脉象细弱，气息微弱不足以呼吸的，情况危急。形体消瘦但脉象洪大，胸中气逆壅盛的，主死。形体与脉气相协调的，主生。脉象参差错乱不调和的，主病。如果三部九候的脉象都相互失守错乱的，主死。上下左右各处的脉象相应，但像捣米一样参差不齐的，病情严重。上下左右脉象完全失调，无法计数的，主死。中
Huangdi said: I have heard of the Nine Pulses (Jiu Hou) from my teacher. The content is numerous and profound, beyond counting. I wish to hear the essential principles so that I may pass them down to my descendants and transmit them to future generations. Let it be engraved in the marrow and stored in the liver and lungs; let us seal this oath with blood and accept it, daring not to leak it lightly. May it accord with the Way of Heaven, having a beginning and an end, corresponding above to the light of heaven and the cycles of stars, and below harmonizing with the nobility and baseness of the Four Seasons and Five Elements, alternating between Yin in winter and Yang in summer. How should humanity correspond to these? I wish to hear the method.
Qibo said: What a wonderful question! This is the supreme number of Heaven and Earth.
Huangdi said: I wish to hear the supreme number of Heaven and Earth.
Qibo said: It begins with One and ends with Nine. One represents Heaven, Two represents Earth, Three represents Humanity. Multiplying this triad by three yields Nine, corresponding to the Nine Regions (Jiu Ye). Thus, the human body is divided into Three Sections (Bu), each containing three pulses (Hou), used to determine life and death, treat the hundred diseases, regulate deficiency and excess, and eliminate pathogenic ailments.
Huangdi said: What are the Three Sections?
Qibo said: There is the Lower Section, the Middle Section, and the Upper Section. Each section has three pulses. These three pulses correspond to Heaven, Earth, and Humanity. One must palpate and guide the observation to grasp the truth. Therefore, in the Lower Section, the "Heaven" pulse examines the Liver, the "Earth" pulse examines the Kidneys, and the "Human" pulse examines the Qi of the Spleen and Stomach.
Huangdi said: How are the pulses of the Middle Section?
Qibo said: There is also Heaven, Earth, and Humanity. The "Heaven" pulse examines the Lungs, the "Earth" pulse examines the Qi of the Chest, and the "Human" pulse examines the Heart.
Huangdi said: With what does the Upper Section examine?
Qibo said: There is also Heaven, Earth, and Humanity. The "Heaven" pulse examines the Qi of the head and angles, the "Human" pulse examines the Qi of the ears and eyes, and the "Earth" pulse examines the Qi of the mouth and teeth.
Each of the three sections has its own Heaven, Earth, and Humanity. Three threes constitute Heaven, three threes constitute Earth, and three threes constitute Humanity. Together they form Nine. The Nine divide into Nine Regions, and the Nine Regions correspond to the Nine Zang Organs. Thus, there are five Spirit Zang (Shen Zang) and four Form Zang (Xing Zang), totaling nine Zang organs. If the essence of the Five Zang organs fails, the complexion will inevitably become dull and lifeless; if the complexion is dull and lifeless, death is certain.
Huangdi said: How do we examine [the condition]?
Qibo said: One must first measure the fatness or thinness of the body to adjust for the deficiency or excess of Qi. In cases of Excess, apply draining methods; in cases of Deficiency, apply tonifying methods. One must first unblock the vessels and collaterals, and then regulate the condition. Regardless of the disease, the goal is to achieve balance.
Huangdi said: How do we determine life and death?
Qibo said: If the body is robust but the pulse is fine and weak, and there is insufficient Qi to breathe, the condition is critical. If the body is emaciated but the pulse is large, and there is excessive Qi in the chest, death ensues. If the body and Qi are in harmony, life prevails. If the pulses are irregular and discordant, disease exists. If the pulses of all three sections and nine positions are mutually disordered, death ensues. If the pulses of the upper and lower, left and right correspond but are uneven like pounding grain, the disease is severe. If the pulses of the upper and lower, left and right are completely disordered and cannot be counted, death ensues. Zhong
