Note 20 — Chapter I · THE CHÁRVÁKA SYSTEM.
Edward B. (Edward Byles) Cowell translation
The upádhi is the condition which must be supplied to restrict a too general middle term, as in the inference "the mountain has smoke because it has fire," if we add wet fuel as the condition of the fire, the middle term will be no longer too general. In the case of a true vyápti, there is, of course, no upádhi.
