大般涅槃經集解 30.32

30.32

案道生曰：難意不許下苦生樂，故以此為徵也。僧亮曰：第三關，若果於輕下之苦而生樂者，一罰比千，千為甚重、一為極輕，而未見應受重苦於輕苦之上，而生樂想者也。故知不以輕苦為樂想也。寶亮曰：此就理為論也。若以人天輕苦為下苦者，應以一罰輕苦為下苦。若爾者，應緣此一罰而生樂也。

Daosheng comments: The objection's intent does not allow that lesser suffering gives rise to pleasure, so he uses this as an examination. Sengliang comments: The third checkpoint: if one truly gives rise to pleasure regarding light and lesser suffering, then comparing one stroke of punishment to a thousand, the thousand is extremely heavy and the one is extremely light; yet we have never seen one who should receive heavy suffering give rise to the notion of pleasure upon the light suffering. Therefore, we know that one does not take light suffering as the notion of pleasure. Baoliang says: This argues in terms of principle. If one takes the light suffering of humans and devas as lesser suffering, one should take the light suffering of one stroke of punishment as lesser suffering. If that were so, one should give rise to pleasure in relation to this single stroke.
