大般涅槃經集解 68.104

68.104

案僧亮曰：有義未彰，重問。煩惱果非煩惱因者，煩惱起有因緣，似過去煩惱為因，現相為緣，因緣皆到。若以無相為緣，則因到緣不到，是果非因，名為梵行也。

Sengliang comments: Because a meaning was not yet clear, he asks again. As for 'a fruit of affliction that is not a cause of affliction', the arising of afflictions has causes and conditions, resembling past afflictions as causes and present characteristics as conditions; causes and conditions both arrive. If one takes the signless as a condition, then the cause arrives while the condition does not arrive; being a fruit and not a cause, it is called holy conduct.
