俱舍論記 24.73

24.73

「有餘師言至感五淨居」者，有餘師言：由信等五次第增上感五淨居。謂或有時信根增上雜修靜慮，或有乃至慧根增上雜修靜慮，隨此差別感五淨居，故唯有五。又《婆沙》云「問：雜修下三靜慮有幾品？有說：但有三品，謂下、中、上，下地無有五淨居果故。如是說者，亦有五品。問：彼無五果，何故有五品因？答：雖無五果，而其彼定法有五品。復次下地雖無五淨居果，而有五品根故。問：因論生論，下三靜慮既有五品雜修，何緣無有五淨居果？答：如非其因、非其器，乃至廣說。復次聖者厭患異生共生處故求生淨居，若下地有淨居者，便於異生共生處所不能厭離，於上處所未離染故。復次聖者厭災患處故求生淨居，下三地中皆有災患故無淨居（廣如彼說）。」問：聖生淨居，造引業不？解云：此論既云熏修有漏令感淨居，明知聖人造牽引業。又《婆沙》異熟因雜修靜慮業引五淨居眾同分。

"Other masters say: [...] project the five Śuddhāvāsa": other masters say that by virtue of the gradual predominance of the five [faculties] beginning with faith, the five Śuddhāvāsa are projected. That is to say: sometimes the faculty of faith is predominant in mixedly cultivating the dhyānas, up to sometimes the faculty of wisdom is predominant in mixedly cultivating the dhyānas; following these distinctions, the five Śuddhāvāsa are projected, and therefore they are only five. Furthermore, the Mahāvibhāṣā states: "Question: How many grades are there in the mixed cultivation of the lower three dhyānas? Some say: there are only three grades, namely inferior, middling, and superior, because the lower stages do not have the five Śuddhāvāsa as their fruit. According to the definitive statement, there are also five grades. Question: Since they do not have the five fruits, why do they have a cause of five grades? Answer: Although they do not have the five fruits, the dharma of those absorptions has five grades. Furthermore, although the lower stages do not have the five Śuddhāvāsa as their fruit, they have five grades of faculties. Question: Raising an argument based on the doctrine: since the lower three dhyānas have five grades of mixed cultivation, for what reason do they not have the five Śuddhāvāsa as their fruit? Answer: Just as it is not the proper cause, nor the proper receptacle, and so on in detail. Furthermore, the noble ones seek rebirth in the Śuddhāvāsa because they loathe places where they would be reborn together with ordinary worldlings (pṛthagjana); if the lower stages had Śuddhāvāsa, then they would not be able to turn away with revulsion from places shared with ordinary worldlings, because they have not yet separated from defilement with respect to higher places. Furthermore, the noble ones seek rebirth in the Śuddhāvāsa because they loathe places of calamity; since in the lower three stages there are calamities in all of them, there are no Śuddhāvāsa" (as explained in detail there). Question: When a noble one is born into the Śuddhāvāsa, do they generate projecting karma (ākṣepaka-karma)? The explanation is: since this treatise states that perfuming and cultivating the sāsrava causes it to project the Śuddhāvāsa, we clearly know that the noble ones do generate projecting karma. Furthermore, the Mahāvibhāṣā states that the karma of the mixedly-cultivated dhyānas, as a fruitional cause (vipāka-hetu), projects the group-homogeneity (nikāya-sabhāga) of the five Śuddhāvāsa.
