47. If one does not comprehend the constancy and variability of the Heavenly Dao (natural laws), but instead claims that the Five Movements and Six Qi do not correspond to the annual cycle, thereby neglecting these theories; once one has grasped the fixed principles of constancy, one must then examine the unpredictable and sudden changes. Regardless of how many complex combined diseases a patient may suffer from, the key lies in understanding them within the context of celestial timing and earthly transformations. He who understands the essence can summarize it in a single statement; he who misses the point will be lost in infinite confusion.
[Note] Physicians in recent times often claim that the Five Movements and Six Qi do not align with actual yearly conditions, and thus abandon their study. This demonstrates a failure to understand the constancy and variability of the Heavenly Dao. The "constancy" of seasons includes: spring warmth, summer heat, autumn coolness, and winter cold. The "constancy" of daily cycles includes: morning coolness, midday heat, evening mildness, and nighttime cold. The "variability" of seasons includes: spring lacking warmth, summer lacking heat, absence of stifling heat, autumn lacking coolness, and winter lacking cold. The "variability" of daily cycles includes: morning mildness, midday cold, evening coolness, and nighttime heat. However, those studying medicine who wish to master the way of constancy and variability must first understand the fixed principles of Host (Zhu) and Guest (Ke) Qi, and then carefully examine unpredictable, sudden changes. Only then can they realize that the myriad complex combinations of pathogenic Qi causing disease cannot escape the laws of celestial timing and earthly transformation. Even when discrepancies occur, one must investigate which phase of celestial timing, which type of earthly transformation, and which specific human pathology correspond to the situation. Treatment should then be administered according to that time, transformation, and pathology, ensuring no errors. This is what is meant by "he who knows the essentials needs only one word to conclude." Should physicians not pay close attention to the theory of Movements and Qi?
