大乘起信論略述 1.171

1.171

論。問曰若心至說究竟滅　述曰。次下釋疑。先問。後答。此初也。謂聞前說境界滅故相應心滅。即謂相應心體亦滅。故作難云。若境滅時相應心體亦隨滅者。心體既滅。業轉現三且未合盡。依何相續。故言若心滅者云何相續。若謂心體不滅盡故令無明相得相續者。心不滅故彼無明相應常相續。云何治道說究竟滅。

Treatise: "Question: If the mind [ceases, how can it continue? If it continues, how can ignorance] be said to cease completely?"
Exposition: Next is resolving doubts. First is the question, followed by the answer. This is the first part. Hearing it said earlier that because objects cease the concordant mind ceases, one assumes that the essence of the concordant mind also ceases, and therefore raises an objection: "If when objects cease the essence of the concordant mind also ceases along with them, since the essence of the mind has ceased, while the three—activity, turning, and manifesting—are not yet due to be exhausted, upon what would they continue? Hence it is said: 'If the mind ceases, how can it continue?' If one says that because the essence of the mind is not completely exhausted it enables the characteristics of ignorance to continue, then since the mind does not cease, those characteristics of ignorance ought to continue perpetually; how then does the path of the antidote say that it ceases completely?"
