3.92

「隨彼有相至定非異熟」者，復通。謂善喜根，此離欲位容有，故言隨彼有相。此無記異熟喜，應類非無，故言此相亦然。於此離欲位中憂，一切種若善、若染無容有故，皆不現行。已離欲者無憂愁故，所以不行。由此準知定非異熟。

On "According as it has a characteristic ... is definitely not karmic maturation": Resolution again: That is to say, the wholesome faculty of joy is admissible in this state of freedom from desire, so it says "according as it has a characteristic." This indeterminate karmic maturation joy, by analogy, should not be nonexistent, so it says "this characteristic is likewise so." In this state of freedom from desire, grief cannot possibly exist in any kind, whether wholesome or defiled, so none of it is active. Since one who is free from desire has no sorrow or grief, it does not become active. From this one can infer that it is definitely not karmic maturation.
