Treating What Hasn't Happened Yet

🔊An earlier lesson in this unit distinguished yangsheng, which operates before any problem appears, from treating disease, which responds to a problem that has already appeared. "Treat what hasn't happened yet" is the classical principle that names exactly this priority explicitly, ranking prevention above cure and describing a physician who waits for illness to fully develop before acting as already working at a disadvantage, no matter how skilled the eventual treatment turns out to be.

🔊The principle is traditionally illustrated with a comparison to two other kinds of waiting too long: digging a well only after becoming thirsty, and forging weapons only after a war has already begun. In both comparisons, the action itself isn't wrong, but its timing has already given away most of its usefulness — the well takes time to dig that a thirsty person doesn't have, and weapons take time to forge that a war already underway doesn't allow for. Treating an illness that has already fully developed is placed in the same category: not a wrong action, but one whose timing has already surrendered much of its potential effectiveness.

🔊This principle also gives a name to what this unit's hidden-pathogen lesson and this course's yangsheng lesson were both circling without stating directly: that Chinese medicine treats the gap between a problem's origin and its visible symptom as the most valuable window for action, precisely because it's the one window every later stage of treatment has already lost. Everything this course has categorized as yangsheng — regular sleep, seasonal eating, moderated emotion, appropriate movement — is, under this principle, an attempt to keep using that window for as long as a life allows, rather than an alternative to medicine for whenever that window finally closes.
