19.113

八辨受俱中，思唯喜俱行，餘五與喜樂捨俱行故，以欲界捨劣故，不與增上思慧俱行，欲界樂不在意地，故亦不俱，此中俱行必未相應，故通於戒，亦可既言受俱非戒者成，故言餘者四也。

Eighth, distinguishing feelings concomitant [with them]: Reflection is concomitant exclusively with joy; because the remaining five are concomitant with joy, pleasure, and equanimity. Since equanimity in the desire realm is inferior, it is not concomitant with superior wisdom arisen from reflection; and pleasure in the desire realm is not present in the mental stage, so it is also not concomitant. Concomitance here does not necessarily mean mental association, so it extends to morality; alternatively, since it speaks of feelings concomitant, it is not established of morality, and thus the remaining ones are four.
