大方廣佛華嚴經疏 17.13

17.13

第八「即自」下各念昔因獲智益也。散緣既止，勝德現前，寂然無思，發宿住智。種善根者，即下十佛曾入此殿，聞法供養故。亦表見自心性，同昔佛故。

Eighth, from "Immediately he himself..." onward, each recalls former causes and obtains the benefit of wisdom. Distracting conditions having ceased, supreme virtues appear before them; tranquil and free of thought, they generate the wisdom of past lives. Planting roots of goodness refers to the ten Buddhas below who once entered this palace, heard the Dharma, and made offerings. It also symbolizes seeing one's own mind-nature to be identical with the Buddhas of the past.
