俱舍論疏 29.57

29.57

論「八中前三至為所緣境」，述解脫境異也。不淨是可憎，淨境名可愛。彼非擇滅者，即是自、上有漏法及類智品道非擇滅也。

The passage of the treatise starting with "Among the eight, the first three... until: as their objective domain" explains the differences in the objects of the liberations. Impurity is repulsive; pure objects are called attractive. "Their non-analytical cessation" (apratisaṃkhyānirodha) refers to the non-analytical cessation of contaminated dharmas of one's own and higher stages, and of the path of the category of subsequent cognition.
