大方廣佛華嚴經隨疏演義鈔 2.8

2.8

疏「念念圓融，類夕夢之經世」者，第八十世隔法異成門。即〈離世間品〉菩薩有十種說三世，謂過去說過去、過去說現在、過去說未來、現在說過去、現在說平等、現在說未來、未來說過去、未來說現在、未來說無盡、三世說一念。前九為別，一念為總，故名十世，以三世相因互相攝故。一念具十，以顯無盡，故一念即無量劫、無量劫即一念。〈普賢行品〉云「無量無數劫，解之即一念。知念亦無念，如是見世間。」如一夕之夢，經於數世。《攝論》云「處夢謂經年，覺乃須臾頃。故時雖無量，攝在一剎那。」〈離世間品〉云「如人睡夢中，造作種種事，雖經億千歲，一夜未終盡。」故莊生夢蝴蝶，假寐百年。事類廣矣。

Regarding the commentary's "Thought-moment by thought-moment perfectly interpenetrating, akin to an evening dream traversing lifetimes": this is the eighth approach, different temporal phases being established in separation throughout the ten periods. That is, in the "Chapter on Leaving the World," the bodhisattva has ten ways of explaining the three periods of time: explaining the past in the past, explaining the present in the past, explaining the future in the past, explaining the past in the present, explaining equality in the present, explaining the future in the present, explaining the past in the future, explaining the present in the future, explaining inexhaustibility in the future, and explaining the single thought-moment in the three periods of time. The previous nine are specific, and the single thought-moment is general; hence they are named the ten periods, because the three periods of time are mutually conditioned and mutually subsume one another. A single thought-moment is endowed with ten to show inexhaustibility; thus a single thought-moment is measureless kalpas, and measureless kalpas are a single thought-moment. The "Chapter on the Practices of Samantabhadra" says: "Measureless and countless kalpas / are understood as immediately a single thought-moment. / Knowing that thought-moments are also no-thought, / one thus sees the worldly realms." It is like the dream of a single evening traversing several lifetimes. The Mahāyānasaṃgraha says: "Dwelling in a dream, one thinks years have passed; / upon waking, it was only a moment. / Therefore, though time is measureless, / it is subsumed in a single kṣaṇa." The "Chapter on Leaving the World" says: "Like a person in a sleeping dream / who performs various deeds: / though hundreds of thousands of years pass, / a single night has not yet ended." Thus Zhuangzi dreamed he was a butterfly, napping for a hundred years. Such instances are vast!
