成唯識論演祕 6.123

6.123

即前二師說伏八地、五地惑也，形滅定故並名為下。若伏八地二種無為，皆非擇滅；若伏五地唯想受滅，不得擇滅，不動無為擇滅所攝，下四地惑並皆斷故。《疏》文總也，應如此知。有疏本云「一地、五地」，「一」字錯也，合為「八」字，有依「一」字作多解釋有多過難，故「八」字正。

This refers to the previous two masters speaking of subduing the afflictions of eight stages or five stages; compared to the attainment of extinction, they are all called 'lower'. If one subdues eight stages, both kinds of unconditioned dharmas (asaṃskṛta) are non-analytical cessation (apratisaṃkhyā-nirodha); if one subdues five stages, only the cessation of ideation and sensation does not obtain analytical cessation (pratisaṃkhyā-nirodha), while the unconditioned [state] of immobility is subsumed under analytical cessation, because the afflictions of the lower four stages are all severed. The text of the Commentary is a general summary; it should be understood in this way. Some editions of the Commentary read 'one stage, five stages'; the character 'one' is an error and should be 'eight'. Some base extensive explanations on the character 'one', producing many faults and objections; hence the character 'eight' is correct.
