俱舍論疏 2.63

2.63

論「如是已說至皆無執受」，第二釋執受、無執受也。文中有三：一明唯無執受界、二通二界、三執受義。此文初也。謂十八界中，七心界、法界、聲界，此九界唯無執受。乘前有所緣中七心界、法界故，別釋七心界及法界名為前八。聲非有所緣法，故言「及聲」。

On the text of the treatise: "Having thus explained… all are not appropriated": This second [part] explains the appropriated and the non-appropriated. In the text there are three [points]: first, clarifying the elements that are exclusively not appropriated; second, [clarifying those that] apply to both; third, the meaning of "appropriated." This is the first text. That is, among the eighteen elements, the seven mind elements, the element of mental objects, and the element of sound—these nine elements are exclusively not appropriated. Following from the preceding [discussion] on having an intentional object that included the seven mind elements and the element of mental objects, it separately explains the seven mind elements and the element of mental objects, terming them "the former eight." Sound is not a dharma that possesses an intentional object; hence it says "and sound."
