唯識二十論述記 2.231

2.231

述曰：未得真智覺，不能自知生死夢所見定非實有，即正理解於此頌文。或為喻顯，如世未覺，不能自知夢心所見定非實有。覺時亦爾，以喻釋難，即此半頌通以法喻二義解之，亦無違也。舊論下句，今在上說。今此上句，舊論下說。舊依梵本，今從唐言，亦無乖返，諸上下頌，應如是知。

Commentary: Before attaining the awakening of true cognition, one cannot know by oneself that what is seen in the dream of saṃsāra is definitely not real; this is the correct principle explaining this verse text. Or it is clarified by analogy: just as in the world, until awakened, one cannot know by oneself that what is seen by the dream mind is definitely not real. It is also like this when awake. Explaining the objection by means of an analogy, this half verse can be understood in both senses of doctrine and analogy without contradiction. The second line of the old treatise is stated first here. What is the first line here was stated second in the old treatise. The old followed the Sanskrit text, while the present follows Chinese word order; there is no discrepancy either; all the verses above and below should be understood in this way.
