大方廣圓覺修多羅了義經略疏 1.914

1.914

躡前也，由見生死、涅槃如夢，即稱圓覺實性同佛境也。此有二意：一、但有能依之夢，必有所依之人，夢是人之神遊，亦見聞之氣分，無別體故；二、但了夢體空無，即證自身真實。迷自身者，由執夢故。大夢之境必有大覺之明故。

This catches up the preceding: because one sees saṃsāra and nirvāṇa as like a dream, this immediately conforms with the real nature of perfect enlightenment as identical to the buddha-realm. This has two meanings: 1. As long as there is a dream that relies upon something, there must be a person upon whom it relies; a dream is the spirit's roaming of a person, and is also the vaporous trace of seeing and hearing, having no separate substance of its own. 2. As long as one understands that the substance of the dream is empty and nonexistent, one directly realizes the reality of one's own body. One who is deluded about one's own body is so due to clinging to the dream. For the realm of the great dream must have the illumination of great enlightenment.
