大方廣佛華嚴經隨疏演義鈔 2.7

2.7

疏「重重交映，若帝網之垂珠」者，第七因陀羅網境界門。如天帝殿珠網覆上，一明珠內萬像俱現諸珠盡，然又互相現影，影復現影，重重無盡故。千光萬色雖重重交映，而歷歷區分，亦如兩鏡互照，重重涉入，傳曜相寫，遞出無窮。

Regarding the commentary's "Layer upon layer mutually reflecting, like the hanging jewels of Indra's net": this is the seventh approach, the realm of Indra's net. Just as the pearl net covering the palace of the king of the gods: within a single bright pearl, ten thousand images all appear, and so it is with all the pearls; and then they mutually manifest reflections, reflections again manifesting reflections, layer upon layer without end. Although a thousand lights and ten thousand colors mutually reflect layer upon layer, they remain clearly distinct. It is also like two mirrors mutually reflecting: layer upon layer interpenetrating, transmitting radiance and transcribing one another, endlessly emerging in alternation.
