唯識二十論述記 2.266

2.266

述曰：下論主答。上句顯理，下顯不同。由在夢位造善、惡心，睡眠所壞，故夢與覺感果不同。

Commentary: Below, the treatise master replies. The first line reveals the principle; the second reveals the difference. Because the mind that performs good and evil in the state of dreaming is impaired by sleep, dreams and waking are different in the results they induce.
