三藏云：末那若無法執所知障者，即大有妨難，如瑜伽說賴耶極少必與一識俱行，如彼二乘學無學人入於滅定無末那者，爾時賴耶唯獨一識不得說言極少二識俱行。又第七十八云：八地已去一切煩惱皆不現行，唯有所知障為所依止，此八地已上意識入人空觀時，末那即起法執名有所知障，是故六七二識皆起二障。

The Tripiṭaka Master says: If manas did not possess the cognitive obscuration of attachment to dharmas, there would be great difficulties. As the Yogācāra states, the ālaya at the very least must operate concurrently with one consciousness. If, when those learners and non-learners of the two vehicles enter the cessation attainment, there were no manas, then at that time the ālaya would operate as a single consciousness alone, and one could not say that at the very least two consciousnesses operate concurrently. Furthermore, the seventy-eighth fascicle states: From the eighth stage onward, no afflictions are active, and only the cognitive obscuration serves as their support. When the mental consciousness of those on the eighth stage and above enters the contemplation of the emptiness of persons, manas immediately gives rise to attachment to dharmas, which is called possessing the cognitive obscuration. Therefore, both the sixth and seventh consciousnesses give rise to both obscurations.
