At a glance

The chapter’s word for the serious illness that does not arise — the one you avoid by following the seasons rather than by any treatment. The transmitted text varies between 苛 and 奇 here; both readings are recorded.

苛 means harsh, exacting, small and persistent — the opposite of a single dramatic event. As a qualifier on 疾 it names the kind of illness that grinds.

The transmitted text is unsettled: the same chapter has 身無奇病 above and 苛疾不起 here, and some editions read 苛 in both places. The variant is recorded rather than resolved here, since the difference does not change the argument.
