何以知春得病？无肝脉也。无心脉，夏得病；无肺脉，秋得病；无肾脉，冬得病；无脾脉，四季之月得病。
假令肝病者，西行，若食鸡肉得之，当以秋时发，得病以庚辛日也。家有腥死，女子见之，以明要为灾。不者，若
感金银物得之。
假令脾病，东行，若食雉兔肉及诸木果实得之。不者，当以春时发，得病以甲乙日也。
假令心病，北行、若食豚、鱼得之。不者，当以冬时发，得病以壬癸日也。
假令肺病，南行，若食马肉及獐鹿肉得之。不者，当以夏时发，得病以丙丁日也。
假令肾病，中央，若食牛肉及诸土中物得之。不者，当以长夏时发，得病以戊己日也。
假令得王脉，当于县官家得之。
假令得相脉，当于嫁娶家得之，或相庆贺家得之。
假令得胎脉，当于产乳家得之。
假令得囚脉，当于囚徒家得之。
假令得休脉，其人素有宿病，不治自愈。
假令得死脉，当于死丧家感伤得之。
何以知人露卧得病？阳中有阴也。
何以知人夏月得病？诸阳入阴也。
何以知人食饮中毒？浮之无阳，微细之不可知也，但有阴脉，来疾去疾，此相为水气之毒也。脉迟者，食干物得之。
问曰∶假令病患欲瘥，脉而知愈，何以别之？师曰∶寸关尺大小迟疾浮沉同等，虽有寒热不解者，此脉阴阳为平复，
当自愈。人病，其寸口之脉与人迎之脉小大及浮沉等者，病难已。
How can one know that a disease was contracted in spring? It is indicated by the absence of the Liver pulse (Gan Mai). If the Heart pulse (Xin Mai) is absent, the disease was contracted in summer; if the Lung pulse (Fei Mai) is absent, it was contracted in autumn; if the Kidney pulse (Shen Mai) is absent, it was contracted in winter; if the Spleen pulse (Pi Mai) is absent, it was contracted during the months of the four seasons (the last eighteen days of each season).
For example, if a person suffers from Liver disease (Gan Bing), it may be caused by traveling westward or consuming chicken meat. Such a disease should manifest in autumn and arise on Geng-Xin days (days associated with Metal). If there is a death due to foul substances at home, and a woman witnesses it, she may suffer disaster due to violating taboos or encountering ominous signs. Alternatively, it may be caused by contact with gold or silver objects.
If a person suffers from Spleen disease (Pi Bing), it may be caused by traveling eastward or consuming pheasant, rabbit meat, and various fruits derived from wood. Otherwise, the disease should manifest in spring and arise on Jia-Yi days (days associated with Wood).
If a person suffers from Heart disease (Xin Bing), it may be caused by traveling northward or consuming pork and fish. Otherwise, the disease should manifest in winter and arise on Ren-Gui days (days associated with Water).
If a person suffers from Lung disease (Fei Bing), it may be caused by traveling southward or consuming horse meat, as well as deer and roe deer meat. Otherwise, the disease should manifest in summer and arise on Bing-Ding days (days associated with Fire).
If a person suffers from Kidney disease (Shen Bing), it may be caused by staying in the central direction or consuming beef and various foods grown in the soil. Otherwise, the disease should manifest in late summer (Chang Xia) and arise on Wu-Ji days (days associated with Earth).
If the Wang pulse (Wang Mai, prosperous pulse corresponding to the current season) is obtained, the disease was likely contracted in an official's household.
If the Xiang pulse (Xiang Mai, secondary prosperous pulse) is obtained, the disease was likely contracted in a household involving marriage or mutual congratulations.
If the Tai pulse (Tai Mai, pregnancy pulse) is obtained, the disease was likely contracted in a household where childbirth or lactation is occurring.
If the Qiu pulse (Qiu Mai, restricted pulse) is obtained, the disease was likely contracted in a prisoner's household.
If the Xiu pulse (Xiu Mai, resting pulse) is obtained, the patient has a chronic condition that will heal spontaneously without treatment.
If the Si pulse (Si Mai, dying pulse) is obtained, the disease was likely contracted through grief and shock while attending a funeral.
How can one know that a disease was contracted from sleeping outdoors? This is because Yin pathogenic factors have invaded the Yang aspect.
How can one know that a disease was contracted in summer? This is because the Yang Qi has entered into the Yin aspect.
How can one know that a disease was caused by food or drink poisoning? Upon superficial palpation (Fu Qu), there is no Yang pulse; the pulse is minute and fine, difficult to discern, showing only Yin characteristics. The pulse comes and goes rapidly, indicating toxicity from water-dampness. If the pulse is slow (Chi), it indicates consumption of dry food.
Question: If a patient is about to recover, how can one determine impending healing through pulse diagnosis? The Master said: If the pulses at the Cun (Cun Kou), Guan, and Chi positions are equal in magnitude, rate (slow/fast), and depth (floating/sinking), even if cold-heat symptoms persist, this indicates that the Yin and Yang of the pulses have returned to balance, and spontaneous recovery should occur. Conversely, if the Cun Kou pulse and the Ying Shou pulse (Ying Shou Mai, located on the neck artery) are equal in size and floating/sinking depth, the disease is difficult to cure.
