大寒厥阴水主初。春分居火二之居。小满少阴分三气。大暑太阴四之乎。秋分阳明五气燥。小雪太阳寒水虚。医师
不能明此理。光阴空读五车书。
初气岁前木主先。二君三相大排连。四来是土常为湿。五气燥金六水寒。
每年进四是客乡。上临十数下临方。寒气热暑出排取。主客胜负定弱强。
初气厥阴风木 二气少阴君火 三气少阳相火
四气太阴湿土 五气阳明燥金 六气太阳寒水
子午少阴君火。卯酉阳明燥金。辰戌太阳寒水。丑未太阴湿土。寅申少阳相火。巳亥厥阴风木。
假如甲辰年。甲化土气。如肾经受病。九月甲戌月为土气。又犯甲己丑未日时死也。余皆仿此。
脉有三部阴阳相乘。荣卫血气。在人体躬。呼吸出入。上下于中。恩息游布。津液流通。随时动作。放象形容。春
弦秋浮。冬沉夏洪。察色观脉。大小不同。一时之间。变无经常。尺寸争差。或短或长。上下争错。或存或亡。病辄改
容。进退低昂。心迷意惑。动失纪纲。惟愿具呈。今得分明子之所问。道之根源。脉有三部。寸尺及关。荣卫流行。不
夫衡铨。肾沉心洪。肺浮肝弦。自此经常。不失铢分。出入升降。漏刻周旋。水下二刻。一周循环。当复寸口虚实见焉。
变化相乘。阴阳相干。风则虚浮。寒则劳坚。沉潜水蓄。支饮急弦。动则为痛。数则热烦设有不应。知变所缘三部不同。
病各异端。大过可怪。不及亦然。邪不空中。中必有奸。审察表里。三焦别焉。知其所合。消息诊看。料度脏腑。独君
神焉。为子孙计。非人莫传。

大寒节气时，厥阴风木之气开始由水气主导。春分时节，少阴君火之气占据第二位。小满时节，少阳相火之气处于第三位。大暑时节，太阴湿土之气位于第四位。秋分时节，阳明燥金之气的第五位表现为燥性。小雪时节，太阳寒水之气的第六位表现为虚寒。医师如果不能明白这些道理，即便读破五车书也是白费光阴。
初之气在岁首之前由厥阴风木主导。第二气为少阴君火，第三气为少阳相火，二者紧密相连。第四气为太阴湿土，性质常为湿。第五气为阳明燥金，性质为燥。第六气为太阳寒水，性质为寒。
每年进入第四气是客气的变化。上位有十数种客气轮流主事，下位则是本气所在。寒气、热暑等客气排出并取用，主气与客气的胜负决定了病势的强弱。初之气是厥阴风木，二之气是少阴君火，三之气是少阳相火，四之气是太阴湿土，五之气是阳明燥金，六之气是太阳寒水。
子年和午年，少阴君火司天；卯年和酉年，阳明燥金司天；辰年和戌年，太阳寒水司天；丑年和未年，太阴湿土司天；寅年和申年，少阳相火司天；巳年和亥年，厥阴风木司天。
假如遇到甲辰年，天干甲化土气。如果肾经受到病变，到了九月甲戌月，又是土气当令。如果再遇到甲己日或丑未日时，病情可能会致死。其余年份都仿照此例推算。
脉诊分为三部，阴阳相互影响，营卫气血存在于人体之中。呼吸出入，气机上下运行于体内，恩泽气息游布全身，津液流通顺畅。随着季节时令的变化而动作，呈现出相应的形象。春季脉象弦，秋季脉象浮，冬季脉象沉，夏季脉象洪。观察面色和脉象，大小各不相同。在一时辰之间，脉象变化无常。寸关尺尺寸争差，脉体或短或长，上下部位交错异常，脉象或存或亡。疾病改变面容，进退低昂不定。心中迷惑，行为失去法度。希望详细陈述，现在让你分明理解你所问的道的根源。脉有三部：寸、尺及关。营卫气血流行，不违背衡量的标准。肾脉沉，心脉洪，肺脉浮，肝脉弦。从此遵循常规，不失毫厘。出入升降，如漏刻计时般周而复始。水下两刻，完成一个循环。回到寸口，虚实之象显现。变化相互乘袭，阴阳相互干扰。风邪则脉虚浮，寒邪则脉劳坚（紧实）。沉潜如水蓄积，支饮则脉急弦。动脉主痛，数脉主热烦。假设有不应验的情况，要知道变化的缘由，三部脉不同，病的端绪各异。太过可怪，不及也是如此。邪气不会空入，中必有所犯。审察表里，三焦分别清楚。知道其所合之处，斟酌诊看，料度脏腑，唯独依靠心神。为了子孙后代打算，不是合适的人不要传授。
At the Great Cold solar term, the Jueyin Wind-Wood qi begins to be dominated by Water qi. At the Spring Equinox, Shaoyin Minister-Fire qi occupies the second position. At the Grain in Ear solar term, Shaoyang Minister-Fire qi is in the third position. At the Great Heat solar term, Taiyin Damp-Earth qi is in the fourth position. At the Autumn Equinox, the fifth position of Yangming Dryness-Metal qi manifests as dryness. At the Light Snow solar term, the sixth position of Taiyang Cold-Water qi manifests as deficiency-cold. If physicians cannot understand these principles, reading five carts of books will be a waste of time.
The first qi is dominated by Jueyin Wind-Wood before the beginning of the year. The second qi is Shaoyin Minister-Fire, and the third qi is Shaoyang Minister-Fire, closely connected. The fourth qi is Taiyin Damp-Earth, with a nature often damp. The fifth qi is Yangming Dryness-Metal, with a nature of dryness. The sixth qi is Taiyang Cold-Water, with a nature of cold.
Entering the fourth qi each year involves the change of guest qi. There are ten or more types of guest qi rotating at the upper level, while the lower level corresponds to the host qi. Host qi and guest qi interact; their victory or defeat determines the weakness or strength of the disease. The first qi is Jueyin Wind-Wood, the second qi is Shaoyin Minister-Fire, the third qi is Shaoyang Minister-Fire, the fourth qi is Taiyin Damp-Earth, the fifth qi is Yangming Dryness-Metal, and the sixth qi is Taiyang Cold-Water.
In Zi and Wu years, Shaoyin Minister-Fire governs the Heaven (Si Tian). In Mao and You years, Yangming Dryness-Metal governs the Heaven. In Chen and Xu years, Taiyang Cold-Water governs the Heaven. In Chou and Wei years, Taiyin Damp-Earth governs the Heaven. In Yin and Shen years, Shaoyang Minister-Fire governs the Heaven. In Si and Hai years, Jueyin Wind-Wood governs the Heaven.
For example, in a Jia-Chen year, the Heavenly Stem Jia transforms into Earth qi. If the Kidney Meridian is diseased, in the ninth month, Jia-Xu month, Earth qi is also dominant. If one further encounters Jia-Ji days or Chou-Wei hours, death may occur. Other years follow this pattern for calculation.
Pulse diagnosis is divided into three positions, where Yin and Yang influence each other. Ying (Nutritive) and Wei (Defensive) Qi and Blood exist within the human body. Respiration enters and exits, Qi moves up and down within the body, nourishing breath spreads throughout, and Body Fluids flow smoothly. Movements change according to seasons, presenting corresponding images. In Spring, the pulse is Xian (Wiry); in Autumn, it is Fu (Floating); in Winter, it is Chen (Deep); in Summer, it is Hong (Surging). Observing complexion and pulse, sizes differ. Within one Shichen (two-hour period), pulse changes are unpredictable. Differences between Cun, Guan, and Chi positions occur; pulses may be short or long, with upper and lower parts disordered, appearing present or absent. Diseases alter facial expressions, advancing or retreating irregularly. One becomes confused and loses discipline. It is hoped that you will state them fully so that you may clearly understand the origin of the Dao you asked about. Pulse has three positions: Cun, Chi, and Guan. Ying and Wei Qi circulate without violating standards. Kidney pulse is Chen (Deep), Heart pulse is Hong (Surging), Lung pulse is Fu (Floating), Liver pulse is Xian (Wiry). Follow these constants, losing not a hair's breadth. Entry and exit, rising and descending, rotate like water clock measurements. Under two ke (48 minutes), one cycle completes. Returning to the Cun Kou (Radial Artery), deficiency and excess become visible. Changes multiply, Yin and Yang interfere. Wind causes Xu (Empty) and Fu (Floating) pulses; Cold causes Lao Jian (Tight/Firm) pulses. Sinking and submersion indicate water accumulation; Zhi Yin (Fluid Retention) causes Ji Xian (Rapid and Wiry) pulses. Dong (Moving) pulse indicates pain; Shuo (Rapid) pulse indicates heat and vexation. If there are discrepancies, know the cause of change; different pulses in the three positions indicate different disease origins. Excess is strange, deficiency is also notable. Evil Qi does not enter empty spaces; if it enters, it must encounter resistance. Examine exterior and interior, distinguish the San Jiao (Triple Burner). Know its combinations, carefully diagnose, estimate Zang-Fu organs, relying solely on Divine Spirit (Shen). For the sake of descendants, do not transmit to unworthy persons.
Left Cun corresponds to Heart and Small Intestine; Left Guan corresponds to Liver and Gallbladder; Left Chi corresponds to Kidney and Bladder. Right Cun corresponds to Lung and Large Intestine; Right Guan corresponds to Spleen and Stomach; Right Chi corresponds to Mingmen (Gate of Life) and San Jiao (Triple Burner).
