不应者，沉细之脉也。甚至极沉极细，几于不可见矣；第
覆病者之手而诊之则见。凡值此不应之脉，乃岁运合宜，命曰
天和之脉，不必求治。若误治之，反伐天和矣。
土运为南政。盖土位居中，面南行令故也。金木水火四运，皆以臣事之，北面受令，故为北政。
甲己二年，为土运南政。（南政之年，南面行令，故其气在南，所以南为上而北为下，故寸为上而尺
为下，司天在上，在泉在下，人气应之，左右皆同。脉有不应者，谓阴之所在，脉乃沉细不应本脉也。
阴者，言六气有三阴三阳，而三阴之位，则少阴居中，太阴居左，厥阴居右。脉之不
应，乃以三阴之中而以少阴所居之处言之，又分南北二政，定其上下也。如遇少
阴司天，则两寸不应。厥阴司天，则右寸不应。太阴司天，则左寸不应。如少阴在泉，则两尺不应。
厥阴在泉，则右尺不应。太阴在泉，则左尺不应。）
乙丙丁戊庚辛壬癸八年，皆为北政。（北政之年，北面受令，其气在北，所以北为上而南为下，在
泉应上，司天应下，人气亦应之，故尺应下而寸应上。如遇少阴司天，则两尺不
应。厥阴司天，则右尺不应。太阴司天，则左尺不应。如少阴在泉，则两寸不
应。厥阴在泉，则右寸不应。太阴在泉，则左寸不应。如尺当不应而反浮大，寸
当浮大而反沉细，寸当不应而反浮大，尺当浮大而反沉细，是为尺寸反。经曰∶“尺
寸反者死。”如右当不应而反浮大，左当浮大而反沉细，左当不应
而反浮大，右当浮大而反沉细，是谓左右交。经曰“左右交者死。”）
不应脉，是指沉细的脉象。甚至极其沉、极其细，几乎无法触及；但只要翻转患者的手进行诊察就能发现。凡是遇到这种不应之脉，说明当年的岁运适宜，被称为“天和之脉”，不需要寻求治疗。如果错误地进行治疗，反而会损伤天和之气。
土运属于南政。因为土位居中央，面南而行令的缘故。金、木、水、火四运，都以臣子的身份侍奉它，面北接受命令，所以称为北政。
甲年和己年，属于土运南政。（南政之年，面南行令，所以气在南面，因此南为上而北为下，所以寸口为上而尺部为下，司天之气在上，在泉之气在下，人气与之相应，左右两侧相同。所谓脉有不应者，是指阴气所在之处，脉象反而沉细，不呈现本应有的脉象。阴气，指的是六气中有三阴和三阳，而在三阴的位置中，少阴居中，太阴居左，厥阴居右。脉象的不应，是就三阴之中少阴所居的位置而言，又分为南政和北政，以确定上下关系。如果遇到少阴司天，则双侧寸口不应。厥阴司天，则右侧寸口不应。太阴司天，则左侧寸口不应。如果少阴在泉，则双侧尺部不应。厥阴在泉，则右侧尺部不应。太阴在泉，则左侧尺部不应。）
乙、丙、丁、戊、庚、辛、壬、癸八年，都属于北政。（北政之年，面北受令，其气在北面，所以北为上而南为下，在泉之气应上，司天之气应下，人气也随之相应，所以尺部应下而寸口应上。如果遇到少阴司天，则双侧尺部不应。厥阴司天，则右侧尺部不应。太阴司天，则左侧尺部不应。如果少阴在泉，则双侧寸口不应。厥阴在泉，则右侧寸口不应。太阴在泉，则左侧寸口不应。如果尺部应当不应却反而浮大，寸口应当浮大却反而沉细，寸口应当不应却反而浮大，尺部应当浮大却反而沉细，这称为“尺寸反”。经文说：“出现尺寸反的情况会死亡。”如果右侧应当不应却反而浮大，左侧应当浮大却反而沉细，左侧应当不应却反而浮大，右侧应当浮大却反而沉细，这称为“左右交”。经文说：“出现左右交的情况会死亡。”）
The "non-responsive" pulse refers to a deep and fine pulse. It may be extremely deep and extremely fine, almost imperceptible; however, it becomes palpable when the patient's hand is turned over for examination. Whenever such a non-responsive pulse is encountered, it indicates that the annual climate cycle is harmonious, known as the "Pulse of Heavenly Harmony," and no treatment is required. Erroneous treatment would instead damage this Heavenly Harmony.
The Earth phase belongs to Southern Governance. This is because Earth resides in the center and issues commands facing south. The Metal, Wood, Water, and Fire phases all serve it as ministers, receiving commands facing north, thus they are referred to as Northern Governance.
The years of Jia and Ji belong to Earth phase with Southern Governance. (In years of Southern Governance, commands are issued facing south, so the Qi is in the South; therefore, South is superior and North is inferior, making the Cun position superior and the Chi position inferior. The Si Tian [Heavenly Sovereign] Qi is above, and the Zai Quan [Earthly Ruler] Qi is below. Human Qi responds accordingly, with the left and right sides being identical. The term "pulse has non-responsiveness" means that where Yin Qi resides, the pulse becomes deep and fine, failing to reflect its normal character. By "Yin Qi," we refer to the Six Qi having three Yin and three Yang phases. Among the positions of the three Yin phases, Shao Yin [Lesser Yin] occupies the center, Tai Yin [Greater Yin] is on the left, and Jue Yin [Terminal Yin] is on the right. The concept of pulse non-responsiveness is discussed regarding the position occupied by Shao Yin among the three Yin phases, further divided into Southern and Northern Governance to determine superiority and inferiority. If Shao Yin is Si Tian, both Cun positions are non-responsive. If Jue Yin is Si Tian, the right Cun position is non-responsive. If Tai Yin is Si Tian, the left Cun position is non-responsive. If Shao Yin is Zai Quan, both Chi positions are non-responsive. If Jue Yin is Zai Quan, the right Chi position is non-responsive. If Tai Yin is Zai Quan, the left Chi position is non-responsive.)
The eight years of Yi, Bing, Ding, Wu, Geng, Xin, Ren, and Gui all belong to Northern Governance. (In years of Northern Governance, commands are received facing north, so the Qi is in the North; therefore, North is superior and South is inferior. The Zai Quan Qi corresponds to the upper part, and the Si Tian Qi corresponds to the lower part. Human Qi also responds accordingly, so the Chi position corresponds to the lower part and the Cun position to the upper part. If Shao Yin is Si Tian, both Chi positions are non-responsive. If Jue Yin is Si Tian, the right Chi position is non-responsive. If Tai Yin is Si Tian, the left Chi position is non-responsive. If Shao Yin is Zai Quan, both Cun positions are non-responsive. If Jue Yin is Zai Quan, the right Cun position is non-responsive. If Tai Yin is Zai Quan, the left Cun position is non-responsive. If the Chi position should be non-responsive but is instead floating and large, or if the Cun position should be floating and large but is instead deep and fine; or if the Cun position should be non-responsive but is instead floating and large, or if the Chi position should be floating and large but is instead deep and fine, this is termed "Reversal of Cun and Chi." The Classic states: "Death occurs with Reversal of Cun and Chi." If the right side should be non-responsive but is instead floating and large, or if the left side should be floating and large but is instead deep and fine; or if the left side should be non-responsive but is instead floating and large, or if the right side should be floating and large but is instead deep and fine, this is termed "Crossing of Left and Right." The Classic states: "Death occurs with Crossing of Left and Right.")
