坐禪三昧經 2.46

2.46

是阿羅漢有九種：退法、不退法、死法、守法、住法、必知法、不壞法、慧脫、共脫。濡智濡進行五種法退，是名退法。利智利進行五種法不退，是名不退法。濡智濡進利，厭思惟自殺身，是名死法。濡智大進自護身，是名守法。中智中進、不增不減處中而住，是名住法。少利智懃精進，能得不壞心解脫，是名必知法。利智大進，初得不壞心解脫，是名不壞法。不能入諸禪，未到地中諸漏盡，是名慧解脫。得諸禪亦得滅禪諸漏盡，是名共解脫。

There are nine kinds of arhat: of the falling dharma, of the non-falling dharma, of the dying dharma, of the guarding dharma, of the abiding dharma, of the dharma of certain knowing, of the indestructible dharma, liberated through wisdom, and doubly liberated. One of weak wisdom and weak vīrya who falls from the practice of the five dharmas is named 'of the falling dharma'. One of sharp wisdom and sharp vīrya who does not fall from the practice of the five dharmas is named 'of the non-falling dharma'. One of weak wisdom and weak vīrya who is sharp in revulsion and contemplation, and commits suicide, is named 'of the dying dharma'. One of weak wisdom and great vīrya who protects himself is named 'of the guarding dharma'. One of middling wisdom and middling vīrya, who neither increases nor decreases but abides in the middle, is named 'of the abiding dharma'. One of slightly sharp wisdom and zealous vīrya who is able to attain indestructible liberation of mind is named 'of the dharma of certain knowing'. One of sharp wisdom and great vīrya who attains indestructible liberation of mind from the very beginning is named 'of the indestructible dharma'. One who cannot enter the dhyānas, but has exhausted all outpourings in the threshold state, is named 'liberated through wisdom'. One who attains the dhyānas and also attains the dhyāna of cessation, exhausting all outpourings, is named 'doubly liberated'.
