注大乘入楞伽經 1.54

1.54

言夜叉王既開悟，虛空宮殿為之讚可，言應如是學，應如是見。如是者，隨順如實之辭也。許其此學、此見皆如實故。諸佛如來見一切法，亦同如是見也。前來既以化境為說法，此復以宮殿為讚可，何也？豈非發真歸源，虛空宮殿，自然消殞。色空依正，同一法界，詎能爾也。

This means that after the yakṣa king attained awakening, empty space and the palace praised and approved him, saying, "You should learn thus; you should see thus." "Thus" is an expression indicating accord with suchness, because it acknowledges that this learning and this view are entirely in accord with reality. The buddhas and tathāgatas, in seeing all phenomena, also see them precisely thus. Previously, [the Buddha] used transformed realms to teach the Dharma, and here the palace also praises and approves; why is this? Is it not that when one brings forth the true and returns to the source, empty space and the palaces naturally dissolve away? How could form and emptiness, dependent [environment] and primary [body], belong to different Dharma realms?
