大般涅槃經義記 8.179

8.179

文中六句攝為三對：初二一對當法分別，「眾生業行不斷不常而得果」者明非無果。業行若常，亦不得果，常不變故；斷亦不得，不生後故。不斷不常方乃得果。「雖念念滅而無所失」明不失因，因體雖復念念盡滅，能生之力常不失也。

The six lines in the text are subsumed under three pairs: The first two form a pair differentiating with regard to dharma: 'Sentient beings' karmic actions are neither cut off nor permanent, yet they obtain retribution' clarifies that retribution is not non-existent. If karmic actions were permanent, they would also not obtain retribution, because the permanent does not alter; if they were cut off, they would likewise not obtain [retribution], because they would not give rise to what follows. Only when neither cut off nor permanent do they thereupon obtain retribution. 'Though perishing from thought-moment to thought-moment, there is no loss' clarifies that the cause is not lost: though the substance of the cause completely perishes from thought-moment to thought-moment, its capacity to produce is never lost.
