俱舍論記 8.4

8.4

「已依三界至處別有幾」者，就〈世品〉中，一明有情世間、二明器世間。就明有情世間中，一總辨有情、二判聚差別。就總辨有情中，一明有情生、二明有情住、三明有情沒。就明有情生中，一明三界、二明五趣、三明七識住、四明九有情居、五明四識住、六明四生、七明中有、八明緣起、九明四有。此下第一明三界，結前問起。於前品末已依三界分別諸心，今次應說三界是何？各自界中處別有幾？

Regarding the passage from "Having already relied upon the three realms..." up to "...how many distinct locations are there?": within the "Loka-nirdeśa", first, the world of sentient beings (sattva-loka) is explained; second, the container world (bhājana-loka) is explained. Within the explanation of the world of sentient beings, first, sentient beings' [modes of existence] are explained in general; second, their various groupings are distinguished. Within the general explanation of sentient beings, first, the birth of sentient beings is explained; second, the abiding of sentient beings is explained; third, the decease of sentient beings is explained. Within the explanation of the birth of sentient beings, first, the three realms are explained; second, the five destinies (gati); third, the seven abodes of consciousness (vijñāna-sthiti); fourth, the nine abodes of sentient beings (sattvāvāsa); fifth, the four stations of consciousness (vijñāna-sthiti); sixth, the four modes of birth (yoni); seventh, the intermediate state (antarābhava); eighth, dependent origination (pratītyasamutpāda); ninth, the four existences (bhava). Below, this first [section] explains the three realms, concluding what came before and introducing the question. At the end of the previous chapter, the various minds were already distinguished based on the three realms; now next, it should be explained: What are the three realms? How many distinct locations are there within each realm?
