俱舍論疏 3.123

3.123

論「意樂喜捨至無異熟」，此釋四根通有漏無漏、通三性。若非無漏非無記者，一向有異熟；若無記無漏者，無異熟。

The treatise says: "The mind, pleasure, joy, and equanimity up to have no vipāka"—this explains that four faculties belong to both the contaminated and the uncontaminated, and to all three moral natures. If they are neither uncontaminated nor indeterminate, they invariably have vipāka; if they are indeterminate or uncontaminated, they have no vipāka.
