Water is the ruling Qi (dominant energy) of winter. Its pulse should correspond to the image of "Quan" (a steelyard weight). "Quan" refers to a steelyard weight, positioned far from the beam and close to the bottom. A deep pulse sinks downward like a stone sinking into water; this represents a harmonious and balanced Qi. If the pulse is excessive, Yang Qi arrives with tension but lacks the stability of the "Quan" image and does not sink into the Ying (Nutrient) level; thus, this is disharmonious Qi, and if too severe, it causes lethargy (pronounced "yi". In *Suwen*, a slow and choppy Chi pulse is called "Jie". Additionally, "Jie Xie" is a disease name characterized by good appetite yet emaciation), pain in the spinal meridians, shortness of breath, and reluctance to speak. The symptom of "Jie Xie" involves pain in the joints of the four limbs, soreness that is unbearable. If the pulse is deficient, it sinks deeper than normal, failing to resemble the "Quan" image; this is also disharmonious Qi. It causes a sensation of the heart hanging empty, coldness in the hypochondrium, bone pain, abdominal fullness, and difficult or incomplete urination. The patient feels sorrowful, as if hungry yet constrained or suspended. (The term "coldness in the hypochondrium" refers to the hollow, soft, and movable area near the lateral costal margin, corresponding to the Miao region where the ribs meet the spine, resulting in central pain due to the emptiness of the two flanks.) The ruling position in the four seasons, whether excessive or deficient, regarding disease manifestations and pulse signs, corresponds to the Central Earth in the Spleen. The Spleen寄旺 (resides and prospers) through the four seasons, irrigating the four directions, and often moves together with the prosperous Qi of the four seasons. When the Qi is prosperous and harmonious, neither excess nor deficiency is observed. The Spleen is the solitary Zang organ, independently governing the four peripheries. Such pathological Qi indicates Spleen excess; without disease, the pulse would not manifest abnormal forms. A pulse that flows like water is termed excessive. If this Qi appears biased in specific seasons, it is sluggish and deviates from the regular meridians. The disease manifests as inability to lift the four limbs, because Spleen prosperity affects the limbs. If the pulse is deficient, sounding like a hum, this indicates Spleen Qi deficiency. It causes obstruction of the nine orifices, named "Zhong Qiang" (heavy stiffness). The disease presents as disharmony among the five Zang organs, leading to dysfunction of the nine orifices. Internal strength indicates overlapping Qi stagnation. This establishes the five Qi of the four seasons, combined with Spleen Earth, totaling five pulses, externally responding to prosperous Qi. Observing the essence of the five colors: mild signs indicate light disease, while severe signs indicate heavy disease, which is of great consequence. If the pulse and complexion are intermixed and chaotic, varying in size, with erratic beat counts indicating danger, and chaotic beat counts suggesting upper pulses surging like a spring while lower pulses are suspended and severed, the pulse gradually becomes superficial and thinned. If both superficial and deep palpations reveal minute pulses, it indicates the absence of Stomach Qi and leads to death. These are all origins of pathological signs. The method of diagnosis and treatment must clarify these major principles of the mechanism. Truly important, do not err. The Scripture of the Divine Mirror and Jade Cabinet concludes here.
