大乘起信論義記 3.215

3.215

問：若據此義，用從真起，何故說言轉識現耶？答：轉識即是梨耶中轉相，依此轉相方起現識現諸境界，此識即是真妄和合。若隨流生死，即妄有功能，妄雖有功，離真不立；若返流出纏，真有功能，真雖有功，離妄不顯。故就緣起和合識中說其用耳。

Question: If based on this meaning, the function arises from the true, why does it say that it is manifested by the evolving consciousness? Answer: The evolving consciousness is precisely the evolving mark in the ālayavijñāna; relying on this evolving mark, it only then gives rise to the manifesting consciousness that manifests all realms of objects; this consciousness is precisely the integration of the true and the deluded. If conforming to the stream of saṃsāra, then the deluded has efficacy; though the deluded has efficacy, it cannot stand apart from the true. If turning against the stream to escape entanglement, the true has efficacy; though the true has efficacy, it is not revealed apart from the deluded. Therefore, its function is spoken of solely with regard to the conditioned arising of the integrated consciousness.
