俱舍論疏 27.170

27.170

論「第二定等至亦得名勝」，述勝劣也。如第二、第三、第四定果，欲界等化心對初定、二定、三定等果上地化心。若以繫地以論，欲等化心劣初禪等化心。若以所依及行，即依上地下地化心，勝依下地上地化心。以二禪欲界化勝初禪，初禪化雖是欲界繫，依第二禪故，從欲界向上行至第二禪故。初禪，初禪化者依初禪故，向上行唯至初禪故。

On the Śāstra's statement: "Those of the second concentration and so on ... also receive the name 'superior'": This explains superiority and inferiority. For instance, the desire-realm and other conjuring minds that are fruits of the second, third, and fourth concentrations, contrasted with the higher-stage conjuring minds that are fruits of the first, second, and third concentrations. If discussed in terms of the stage to which they are bound, the desire-realm and other conjuring minds are inferior to the conjuring minds of the first dhyāna, etc. But in terms of basis and practice, a lower-stage conjuring mind based on a higher stage is superior to a higher-stage conjuring mind based on a lower stage. This is because the desire-realm conjuration of the second dhyāna is superior to the first dhyāna's conjuration of the first dhyāna: although it is bound to the desire realm, it is based on the second dhyāna, and its upward reach from the desire realm extends to the second dhyāna; whereas for the first dhyāna's conjuration of the first dhyāna, because it is based on the first dhyāna, its upward reach extends only to the first dhyāna.
