一种说法以尺脉为根。人的尺脉，就像树木的树根一样，水是天一的源头，是先天生命的根本。王叔和说：“寸脉和关脉虽然摸不到，只要尺脉还存在，像这样的病人，虽然令人担忧可能死亡，但称为‘有根’。”如果肾脉单独败绝，那就是无根了。另一种说法以沉取（重按）为根。《内经》说：“各种脉象浮取而没有根的，都是死证”，这叫做只有表证没有里气，这叫孤阳不能化生造化。之所以万古不息的原因，在于一阴一阳互相作为根本。阴气既然断绝了，孤阳怎么能独自存在呢？这两种说法看似不同，但实际上是一致的。两尺部对应肾脏区域，沉取时，六脉都反映肾的状态。那么两尺部的无根与沉取时的无根，总归都是肾水绝灭的表现。
脉，是气血的先导。气平和则脉象调和，气盛则脉象洪大，气衰则脉象微细，气滞则脉象涩滞，气缩则脉象短小，气亏则脉象虚弱，气急则脉象急促，气大则脉象长，气搏则脉象浮，气郁则脉象沉，气寒则脉象迟，气数（快），气结则出现歇止脉。如果用脉象的盛大来考察各种疾病的根源，没有不得出其真实情况的。左寸脉盛，是风寒邪气。右寸脉盛，是痰火邪气。左关脉盛，是气机郁滞。右关脉盛，是内伤。左尺脉盛，是房事过度。左尺脉盛（注：原文此处重复提及左尺，结合后文语境及常见医理，通常左尺主肾阴/精血，右尺主命门/元气，或指代不同劳损，此处依原文直译），是体力劳动过度。两寸脉俱盛，是伤风生痰。两关脉俱盛，是气郁兼伤食。两尺脉俱盛，是房劳兼体力劳动过度。左寸与右关脉盛，是风寒挟带食积。左寸与右尺脉盛，是劳力受寒。右寸与左关脉盛，是气郁生痰。右寸与左尺脉盛，是阴虚火动。左寸与左关脉盛，是感寒郁气。左寸与左尺脉盛，是房劳受寒。右寸与右关脉盛，是食积生痰。右寸与右尺脉盛，是劳伤元气、感受风邪。左关与右尺脉盛，是气郁劳伤。左关与左尺脉盛，是房劳郁气。右关与左尺脉盛，是醉饱后行房。右关与右尺脉盛，是饱食后从事劳役。又有六脉皆浮的是风邪，滑的是痰饮，迟的是冷证，濡的是湿邪，洪的是火邪，紧的是痛证，沉的是气病，数的是热证，弦的是寒证，弱的是虚证，芤的是失血，涩的是少气，弦紧的是风寒，微弱的是阳虚，短缩的是阴虚，浮滑的是风痰，洪大的是火邪，弦大的是实热，实大的是有余（实证），虚大的是不足（虚证）。
One theory regards the Chi pulse (尺脉, radial pulse position at the wrist) as the root. The human Chi pulse is like the root of a tree; water is the origin of Heavenly One, which is the root of innate life. Wang Shuhe said, "Even if the Cun (寸脉, distal pulse position) and Guan (关脉, middle pulse position) pulses are imperceptible, as long as the Chi pulse remains unceasing, such a case, though worrying of potential death, is called 'having a root'." If the Kidney pulse alone fails, it is without a root. Another theory regards deep palpation (Chen Hou 沉候, heavy pressure) as the root. The Classics state, "All pulses that are superficial and lack a root indicate death"; this is called having exterior but no interior, known as isolated Yang unable to generate transformation. What makes things ceaseless for eternity is the mutual rooting of Yin and Yang. If Yin is extinguished, how can isolated Yang exist alone? These two theories seem different but are actually consistent. The bilateral Chi positions correspond to the Kidney region; upon deep palpation, all six pulses reflect the state of the Kidneys. Therefore, both the absence of a root in the bilateral Chi positions and the absence of a root upon deep palpation ultimately signify the exhaustion of Kidney Water.
The pulse is the precursor of Qi and Blood. When Qi is balanced, the pulse is harmonious; when Qi is excessive, the pulse is surging (Hong Mai 洪脉); when Qi is deficient, the pulse is minute (Wei Mai 微脉); when Qi is stagnant, the pulse is choppy (Se Mai 涩脉); when Qi contracts, the pulse is short (Duan Mai 短脉); when Qi is depleted, the pulse is empty (Xu Mai 虚脉); when Qi is rapid, the pulse is hurried (Cu Mai 促脉); when Qi is expansive, the pulse is long (Chang Mai 长脉); when Qi struggles, the pulse is floating (Fu Mai 浮脉); when Qi is constrained, the pulse is deep (Chen Mai 沉脉); when Qi is cold, the pulse is slow (Chi Mai 迟脉); when Qi is frequent (Shu Mai 数脉), and when Qi knots, intermitted pulses appear. By observing the excessiveness of the pulse to investigate the origins of diseases, one will invariably grasp their true nature. Excess in the Left Cun position indicates Wind-Cold. Excess in the Right Cun position indicates Phlegm-Fire. Excess in the Left Guan position indicates Qi stagnation. Excess in the Right Guan position indicates internal injury. Excess in the Left Chi position indicates sexual exertion. Excess in the Left Chi position [Note: Text repeats Left Chi, likely implying labor strain in context] indicates physical labor exertion. Excess in both Cun positions indicates wind injury generating phlegm. Excess in both Guan positions indicates Qi stagnation with food retention. Excess in both Chi positions indicates combined sexual and physical labor exertion. Excess in the Left Cun and Right Guan positions indicates Wind-Cold complicated by food retention. Excess in the Left Cun and Right Chi positions indicates cold invasion due to labor. Excess in the Right Cun and Left Guan positions indicates Qi stagnation generating phlegm. Excess in the Right Cun and Left Chi positions indicates Yin deficiency with Fire agitation. Excess in the Left Cun and Left Guan positions indicates cold invasion with Qi constraint. Excess in the Left Cun and Left Chi positions indicates cold invasion due to sexual exertion. Excess in the Right Cun and Right Guan positions indicates food retention generating phlegm. Excess in the Right Cun and Right Chi positions indicates Qi depletion from labor with wind pathogen invasion. Excess in the Left Guan and Right Chi positions indicates Qi stagnation and labor injury. Excess in the Left Guan and Left Chi positions indicates Qi constraint due to sexual exertion. Excess in the Right Guan and Left Chi positions indicates sexual activity after drunkenness or overeating. Excess in the Right Guan and Right Chi positions indicates labor strain after full meals. Furthermore, all six pulses being floating indicates Wind; slippery indicates Phlegm; slow indicates Cold; soggy indicates Dampness; surging indicates Fire; tight indicates Pain; deep indicates Qi disorder; rapid indicates Heat; wiry indicates Cold; weak indicates Deficiency; knifelike (Kou Mai 芤脉) indicates blood loss; choppy indicates scanty Qi; wiry and tight indicates Wind-Cold; weak and thin indicates Yang deficiency; short and contracted indicates Yin deficiency; floating and slippery indicates Wind-Phlegm; surging and large indicates Fire pathogen; wiry and large indicates Excess Heat; solid and large indicates Excess (Shi Zheng 实证); empty and large indicates Deficiency (Xu Zheng 虚证).
