俱舍論疏 22.49

22.49

The treatise says: "As with feeling, the conditioned formations conforming to feeling are likewise so"—this second part explains that the conditioned formations conforming to feeling share the same meaning as feelings. The Nyāyānusāra says: "However, that which the Bhagavān stated in the sūtra, that 'unpleasant feeling is suffering when arising and when persisting,' is because that unpleasant feeling is suffering by its nature. As for 'pleasure when deteriorating,' when unpleasant feeling deteriorates, even if there is no pleasant feeling, because of the cessation of unpleasant feeling it appears like pleasure; therefore it is also called pleasure. Because the designation 'deterioration' is established for the phase of the cessation of the continuum, when unpleasant feeling ceases it is called the deterioration of unpleasant feeling (not momentary destruction). And so forth, pleasant feeling is pleasant when arising and when persisting because that pleasant feeling is pleasant by its nature. As for 'suffering when deteriorating,' ordinary beings, when not yet detached from defilement, constantly seek pleasure in their minds; at the phase of the deterioration of pleasure, sorrow and the like arise, and therefore pleasant feeling is spoken of as the nature of the suffering of deterioration. When pleasant feeling deteriorates, even if there is no unpleasant feeling, it appears like suffering and also constitutes suffering. Neither-unpleasant-nor-pleasant feeling is neither suffering nor pleasure when arising and when persisting, because its nature is that [neutrality]. When it deteriorates, as either suffering or pleasure is capable of becoming manifest, it can be said to have both suffering and pleasure; at the time of deterioration it is impossible to have both; therefore the Buddha made a different explanation regarding this, saying that it is suffering without wisdom, and the arising of wisdom is pleasure. Because without wisdom it expands, this feeling is accompanied and increased by ignorance. Because of the lack of wisdom, within the bad destinies and the like, limitless suffering of conditioned formations completely arises; because it is extremely subtle, it is very difficult to perceive, and only noble ones are capable of perceiving it. Therefore there is a verse." The verse cited is identical to that in this treatise.
