「有說隨眠至非所隨增」者，敘異說。此約隨順解隨增。有說：隨眠是隨順義，非無漏境順諸隨眠，非上地境順諸下隨眠，故雖是所緣，而無隨增理。如風病人服乾澁藥，病人於藥不相隨順，非所隨增。藥於病人無有勢力，非能隨增。病人喻境，藥喻能緣惑。此中正取風病人為喻，非取風病。若將風病望乾澁藥，相隨順故，有所隨增。

As for "Some say that anuśaya ... is not what increases through adherence": This relates an alternative view. This explains "increase through adherence" in the sense of accord (anuvartana). Some say: "Anuśaya" has the meaning of according with. Uncontaminated objects do not accord with the anuśayas, nor do objects of the upper stages accord with lower anuśayas; therefore, although they are objects, there is no possibility of increasing through adherence. Like a patient with a wind illness who takes dry, astringent medicine: the patient does not accord with the medicine, so there is no increase through adherence [to the illness]; the medicine has no power over the patient, so it is not what can increase through adherence. The patient is the metaphor for the object; the medicine is the metaphor for the afflictions taking it as object. Here, the patient with a wind illness is specifically taken as the metaphor, not the wind illness itself. If one considers the wind illness with respect to the dry, astringent medicine, because they accord with each other, there is increase through adherence.
