成唯識論述記 10.222

10.222

述曰：十地修道位中亦伏煩惱斷彼麁重，而非正意，所以者何？不斷隨眠故此不說。《攝論本》及世親等說，十地菩薩留煩惱障助願受生，故非正意，意趣於智斷所知障，故斷隨眠，不斷煩惱之隨眠也。問：若爾，何故初地但說異生性障，不說更斷修道障也？

The Commentary states: Although in the stage of the path of cultivation of the ten grounds one also suppresses afflictions and severs their unserviceability, this is not the primary intention. Why is that? Because one does not sever latent dispositions, this is not mentioned. The Root Mahāyānasaṃgraha, Vasubandhu, and others state that bodhisattvas of the ten grounds retain the affliction obstacle to support vows and take rebirth; hence it is not the primary intention. The intention is directed toward wisdom to sever the cognitive obstacle, and so one severs latent dispositions, but does not sever the latent dispositions of affliction. Question: If so, why does the first ground speak only of the obstacle of ordinary-personhood, and not speak of further severing the obstacles of cultivation?
