第四明退緣有十。馬勝者，則舊俱舍云：黑齒比丘名阿輪，實應言阿濕縛，此云馬，伐多此云勝，與梵王論義比丘也。獲敬養故退，如提婆達多者，天授利根，何故退耶？

Fourth, clarifying the ten conditions for regression. Regarding Aśvajit: the old Kośa says: 'The black-toothed monk named Aluṇ'; in reality it should be called Aśva, which here means 'horse', and jita, which here means 'conquering'; he was the monk who debated with Brahmā. Regressing due to obtaining veneration and offerings: as in Devadatta; Devadatta had sharp faculties, so why did he regress?
