[Physical Characteristics] The Ru (Soft) pulse is fine and soft, appearing in the floating position; it can be felt with light pressure but feels empty upon heavy pressure.
Ru means the image of softness. It must be observed as fine and soft at the floating level (light pressure); it cannot be seen at the middle level (moderate pressure) or deep level (heavy pressure). Wang Shuhe compared it to "silk floating on water," and Li Shizhen compared it to "bubbles floating on water," both describing its characteristic of disappearing upon pressing.
[Indications] The Ru pulse primarily indicates Yin deficiency, exhaustion of marrow, and injury to essence. A Ru pulse at the left Cun position indicates forgetfulness and palpitations. A Ru pulse at the left Guan position indicates blood failing to nourish the tendons. A Ru pulse at the left Chi position indicates withered and damaged essence and blood. A Ru pulse at the right Cun position indicates loose interstices and spontaneous sweating. A Ru pulse at the right Guan position indicates Spleen deficiency with dampness invasion. A Ru pulse at the right Chi position indicates failure of Mingmen fire and impending death.
Generally, a floating pulse relates to the Qi aspect; being detectable with light pressure suggests that Qi has not yet failed. A deep pulse relates to the Blood aspect; feeling absent upon heavy pressure suggests the decline of essence and blood. In cases of chronic illness or in the elderly, although this pulse appears, it does not necessarily mean imminent death, because the pulse matches the symptoms. However, if seen in healthy individuals, the young and vigorous, or in acute illnesses, it is called a Rootless Pulse, indicating that death is near. Wang Shuhe stated, "Felt with light hand, absent upon pressing." Conversely, the spurious *Mai Jue* states, "Seems present upon pressing, absent upon lifting." How contrary to reason! Moreover, if it seems present upon pressing but absent upon lifting, this is the Ruo (Weak) pulse, not the Ru pulse. The floating softness of the Ru pulse is similar to the Xu (Deficient) pulse, but the Xu pulse is large in form while the Ru pulse is small. The fineness of the Ru pulse is similar to the Ruo pulse, but the Ruo pulse appears in the deep position while the Ru pulse appears in the floating position. The rootlessness of the Ru pulse is similar to the San (Scattered) pulse, but the San pulse goes from floating-large to gradually deep, whereas the Ru pulse goes from floating-small to gradually invisible; going from large to deep is entirely ominous, while going from small to invisible is half auspicious and half ominous. Additionally, the Ru pulse also governs bone-steaming heat in the four limbs, caused by the exhaustion of Kidney Qi, where Water fails to control Fire.
[Physical Characteristics] The Ruo (Weak) pulse is fine and small, appearing in the deep position; it is absent upon light pressure but felt upon heavy pressure.
It is deep, fine, and small; the body is not full, and the momentum does not surge.
[Indications] The Ruo pulse indicates sinking of Yang and weakness of true Qi. A Ruo pulse at the left Cun position indicates palpitations and forgetfulness. A Ruo pulse at the left Guan position indicates dry Liver Wood and tendon spasms. A Ruo pulse at the left Chi position indicates dried-up flow (Kidney Yin/Essence depletion). A Ruo pulse at the right Cun position indicates spontaneous sweating and shortness of breath. A Ruo pulse at the right Guan position indicates deficiency in processing food and drink. A Ruo pulse at the right Chi position confirms the sinking of Yang.
Floating pulse is used to examine Yang; Yang governs the Qi aspect. If it is absent upon light pressure, then Yang Qi is severely deficient, which is undeniable. Yang Qi serves to protect the exterior and consolidate; it also circulates through the Triple Burner and ripens the five grains. Liu said: "Qi deficiency leads to a weak pulse. Weakness at Cun indicates Yang deficiency, at Chi indicates Yin deficiency, at Guan indicates Stomach deficiency. When the Ruo pulse presents this form, Yin pathogens are extremely abundant; unless Yang returns, how can Yang recover?" The *Su Wen · Yu Ji Zhen Zang Lun* states: "A pulse that is weak and slippery indicates the presence of Stomach Qi. A pulse that is weak and choppy indicates a chronic illness." I believe that the Ruo pulse can be pressed heavily, suggesting that Yin has not yet perished; if accompanied by a Choppy (Se) quality, then Qi and Blood are mutually failing, and physiological life is extinguished. Zhang Zhongjing said: "When Yang sinks into Yin, there should be aversion to cold and fever. Seen in chronic illness and old age, it can still be supported; seen in new illness and youth, death is inevitable!"
According to the *Mai Jing*: "The Ruo pulse is extremely soft, deep, and fine; it is obtained only upon pressing and is absent upon lifting." How clear and detailed! The spurious *Mai Jue* claims it is "obtained with light hand," which clearly contradicts Wang Shuhe. Furthermore, this describes the form of the Ru pulse, not the image of the Ruo pulse. Thus, we know that the spurious *Mai Jue* mistakenly identified the Ru pulse as Ruo and the Ruo pulse as Ru, showing extreme carelessness. Even Li's metaphor of floating bubbles follows the errors of Gao Yangsheng and requires careful verification.
