成唯識論述記 5.49

5.49

述曰：此第二，以因中識難。《攝論》第三說，異熟心依染污意。無性染意，即是第六；世親染意，或第七心，故知第八亦依六、七。此約異生、一分有學菩薩受生，如《對法》第五：有是願力者，此要十地大菩薩眾為度有情，若分段，若變易，亦由二智善心為緣，第八得起。此說通初地，或說在八地，前說為勝。

The Commentary states: This is the second, an objection using the vijñāna in the causal state. The third fascicle of the Mahāyānasaṃgraha says that the vipāka mind relies on the defiled manas. In Asvabhāva's view, the defiled manas is the sixth; in Vasubandhu's view, the defiled manas is perhaps the seventh mind; hence one knows that the eighth also relies on the sixth and seventh. This is said with respect to pṛthagjanas and a portion of śaikṣa bodhisattvas taking birth, as in the fifth fascicle of the Abhidharma-samuccaya: for those who have the power of vows, this requires the assembly of great bodhisattvas on the ten bhūmis, in order to cross over sentient beings, whether through mortal birth or transformational birth, also taking the wholesome minds of the two wisdoms as condition, whereby the eighth is able to arise. This explanation applies generally to the first bhūmi, or is said to be on the eighth bhūmi; the former explanation is superior.
