The intricate network of meridians circulating within the body is known as the bloodstream. Its ceaseless flow, akin to the perpetual motion of rivers, embodies an unceasing vitality. It is often said that “the bloodstream is akin to the meandering rivers.” Here, the inquiry arises: how might one observe and assess these internal pathways, discerning their quality and forecasting their destiny? Conventionally, such scrutiny relies on the external manifestations of “form” and “hue.”
Regarding form, despite the concealed nature of the bloodstream within the corporeal confines, certain aspects manifest superficially on the skin’s surface. The fundamental tenet concerning these manifestations dictates that they are best concealed rather than conspicuous. Ancient maxims caution: “When the sinews of the forehead protrude like earthworms, it signifies poverty and adversity.” Others opine: “A coarse and lean physique betrays a life mired in indigence.” Further still, it is proclaimed: “When sinews and vessels stand out prominently, misfortune looms.” Similarly, “Exposed sinews on the back of the hand portend a lifetime of toil.” These adages, steeped in wisdom, offer invaluable insights.
In terms of hue, the adage “pale complexion betrays deficient blood” holds true. Those afflicted with anemia often exhibit pallor, typically stemming from poor dietary habits, irregularities in lifestyle, or insufficient rest and exercise. Observing such a complexion, one may aptly deduce, in conjunction with other circumstances or factors, the trajectory of an individual’s fate. Individuals afflicted with hypertension often exhibit a complexion of varied hues, predominantly crimson and stagnant, particularly exacerbated during sweltering climates, where the fiery flushes ascend, portraying a manifestation of aridity vividly discernible. Should their astrological alignment prove unfavorable, or if a certain month of the year debilitates them most, it is prognosticated that they may succumb to cerebral hemorrhage during said month, a prognosis seldom errant. Concurrently, an appraisal of their temperament, evident in the fluctuation of their countenance with emotional vicissitudes, affords insight into their character, thereby facilitating an assessment of their prospects, a method of discernment deemed considerably reliable. In antiquity, during the Warring States period, Tian Guang of Yan once expounded upon the attendants of Crown Prince Dan, observing, “Upon clandestine observation, those deemed ineffectual among the prince’s retinue exhibit a ruddy countenance when enraged—Summer fosters those of sanguine courage, whose visage reddens with wrath; while those of Song reveal a cyanotic hue; as for Wuyang (also known as Qin Wuyang), individuals of robust constitution, their countenance pales with anger. Yet, with regards to Jing Ke, renowned for his valor, his complexion remains unaltered despite his ire.” Tian Guang thus emerges as an adept practitioner of physiognomy. In sum, the aphorism “Blood manifests splendor, pulses veil secrets” encapsulates the enigmatic art.
