1.484

體是常住，能生果者，父母地、水、火、風及德中十種通常者，并有能句，常，能生果。破此量云：此等亦應體是無常；許能生果故；如所生果。子微已去皆能生果，體無常故。又宗如前；許有生果之作用故；如所生果。或總相言：諸句義中能生果，常者應是無常，有作用故，如所生果。

Those whose substance is eternal and capable of producing effects are: the parental earth, water, fire, and wind; the ten kinds among qualities that are generally eternal; together with the category of potency, which is eternal and capable of producing effects. The inference refuting these states: These should also be impermanent in substance; because you admit they can produce effects; like the effects produced. Secondary atoms and onward can all produce effects, because their substances are impermanent. Again, the thesis is as before; because you admit they possess the activity of producing effects; like the effects produced. Or, stating it in general terms: Among the categories, those that can produce effects and are eternal should be impermanent, because they have activity, like the effects produced.
