成唯識論述記 9.61

9.61

述曰：又若有漏心皆有法執，法執之心必有勢力，應異熟生心亦是能熏；有漏之心有勢用故；如善、惡等。然汝執第八亦非能熏，是異熟心無勢用故，不見有執勢用之心，無能熏者。應第八識亦是能熏，不爾，便與比量相違。若爾，何故《楞伽》、《中邊》上卷等言，三界八識皆妄分別？《顯揚》十六說亦同此。

The Commentary states: Furthermore, if all defiled minds possessed dharmagrāha, a mind with dharmagrāha would necessarily have efficacy, and thus a mind born of maturation should also be capable of perfuming, because a defiled mind has efficacy and function, like wholesome, unwholesome, and so on. Yet you maintain that the eighth consciousness is also not capable of perfuming because as a mind of maturation it lacks efficacy and function. But no mind with grasping and efficacy is ever seen to lack the capacity to perfume. Thus the eighth consciousness should also be capable of perfuming; otherwise, it would contradict inference (anumāna). If so, why do the Laṅkāvatāra-sūtra, the upper fascicle of the Madhyāntavibhāga, and so forth state that the eight consciousnesses in the three realms are all false discrimination? Fascicle sixteen of the Prakaraṇāryavācā also states the same.
