首楞嚴義疏注經 9.172

9.172

前文云「漚滅空本無，況復諸三有。」故知眾生共業所感國土及空，一人返妄歸真，始覺合本，其所感者隨妄消殞。前文云「諸器世間應念化成無上知覺。」然發真者合覺之時，雖但見覺，無妄可生。此無生妄，未發真者見是實有。其妄所感共變國土為智所了，寧不振裂？由是諸佛成道，動諸世界，必不徒然。

The earlier text states: 'When the bubble perishes, space itself originally does not exist; how much less the various three realms of existence?' Hence we know that the lands and space produced by the collective karma of sentient beings, when one person turns away from delusion and returns to reality—the initial awakening merging with the fundamental—what is produced follows the delusion into extinction. The earlier text states: 'The various receptacle worlds instantly transform into unexcelled knowledge and perception.' Yet, when the one who brings forth reality unites with enlightenment, although he sees only enlightenment and no delusion can arise, this delusion that is unarisen is seen as truly existent by those who have not brought forth reality. The mutually transformed lands produced by their delusion are fully comprehended by wisdom—how could they not quake and split? Therefore, when the Buddhas achieve the Way and shake all worlds, it is certainly not in vain.
