俱舍論疏 26.201

26.201

論「四第九解脫至未來修九」，四第九者，謂前四種性。第九解脫，同盡智初，唯緣非想故，所以苦、集、類、盡隨應現修。隨應現修者，謂苦、集智隨一起不定；類、盡決定，非隨應也。「未來修九」者，加世俗智，同得應果故。

Regarding the passage of the śāstra from “The four ninth liberations” up to “in the future cultivates nine”: “The four ninths” refers to the first four lineages. The ninth liberation path, like the initial [moment of] the knowledge of exhaustion, takes only neither-perception-nor-non-perception as its object, and therefore [the knowledges of] suffering, origin, subsequent, and exhaustion are presently cultivated according to applicability. “Presently cultivated according to applicability” means that either the knowledge of suffering or of origin arises indeterminately, whereas subsequent and exhaustion [knowledges] are determinate and not “according to applicability.” “In the future cultivates nine” means adding conventional knowledge, because they equally attain the fruit of an arhat.
