俱舍論記 23.124

23.124

「此預流名至應名預流」者，問。此預流名為目何義？若初得聖道名為預流，即預流名應名第八。第八者，謂預流向也。四向四果從後向前，初向第八。故《婆沙》四十六云「第八聖者，謂隨信行及隨法行，從勝數之是第八故。」又解：於八忍中從後向前數，苦法忍為第八，故《智度論》說見道名八人地。若初得果名為預流，則倍離欲、全離欲者，至道類智得一來果、得不還果，此亦初得，應名預流。

Regarding the passage [beginning with] "Does this name 'stream-enterer' [...] ought to be called a stream-enterer?": This is a question. What meaning does this name "stream-enterer" designate? If it means first attaining the noble path, then the name "stream-enterer" should designate the eighth [person]. The "eighth" refers to the candidate for stream-entry. Counting from the last toward the first among the four candidates and four fruits, the first candidate is the eighth. Therefore the *Mahāvibhāṣā*, fascicle 46, states: "The eighth noble one refers to the follower by faith and the follower by Dharma; counting from the superior, this is the eighth." Another explanation: Counting backward among the eight patiences, the patience with the Dharma of suffering is the eighth; therefore the *Mahāprajñāpāramitopadeśa* states that the path of seeing is called the stage of the eighth person. If [the name] designates first attaining a fruit, then when one detached from half [of desire] or wholly detached from desire reaches the subsequent knowledge of the path and attains the fruit of once-returner or the fruit of non-returner, this is also a first attainment and ought to be called stream-entry.
