In that case, because the ascertainment of a negation is preceded by the ascertainment of an affirmation, the cognition of pervasion—which is of the nature of a relation qualified by the absence of an extrinsic condition—arises only when the cognition of the extrinsic condition has occurred, and the cognition of the extrinsic condition depends upon the cognition of pervasion; thus the fault of mutual dependence, like a thunderbolt blow, sticks firmly as cement. Therefore, because invariable concomitance is difficult to comprehend, there is no scope for inference and the rest. The purposeful activity directed toward fire and the like immediately following the cognition of smoke and the like is explained either as having perception as its root or as an illusion. The occasional attainment of the fruit, however, is accidental, just like [the effects of] gems, mantras, and herbs. Therefore, what is to be proved by that—unseen merit and demerit, and the like—does not exist either.
