2.46

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'.
