大方廣佛華嚴經疏 17.15

17.15

第十「爾時世尊」下殿皆廣博，即示如意相。廣殿同處以遣局情，亦表廓大慈悲等眾生界。又如來入殿，即覺智現前。忽然廣博，則身心無際。十方已下結無盡，唯結後四，前已結故。

Tenth, from "At that time, the Bhagavat" onward, all the palaces become vast and extensive, which demonstrates the mark of wish-fulfillment. The vast palaces occupy the same place in order to dispel limited and biased sentiments, and also to symbolize broadening great compassion to be equal to the realm of sentient beings. Furthermore, when the Tathāgata enters the palace, enlightened wisdom immediately becomes manifest. Their sudden vastness and extensiveness signifies that body and mind are without boundary. From "ten directions" onward, it concludes with infinity; it concludes only the latter four [directions], because the preceding ones have already been concluded.
