俱舍論疏 24.135

24.135

論「無學異生亦成就故」，答也。擇滅無為若是有學，因何異生、無學皆得成就？若是有學？即雜亂也。

On the Śāstra's statement: "Because non-learners and ordinary worldlings also possess it": This is the answer. If the unconditioned [attainment of] analytical cessation (pratisaṃkhyā-nirodha) were learning, why would ordinary worldlings and non-learners both possess it? If it were learning, there would be confusion [of categories].
