注維摩詰經 1.366

1.366

什曰：梵本云「空中造立宮室自在無礙」。空不可用為宮室，如是不離眾生得淨國也。又云：空中得為宮室，不可用空為宮室，要用材木然後得成。如是菩薩雖解於空，不可但以空心得，要以三因成其國也。又意異故，經文不同也。生曰：造立宮室，譬成就眾生也。空地是無妨礙處，譬取無穢，穢則礙也。

[Kumāra]jīva says: The Sanskrit text says 'erecting a palace in empty space freely and without hindrance'. Emptiness cannot be used as a palace; similarly, without sentient beings one cannot attain a pure land. Furthermore, it says: in empty space one can make a palace, but one cannot use empty space to make a palace—one must use timber and wood before it can be completed. Likewise, although a bodhisattva understands emptiness, he cannot attain it merely with an empty mind; he must use the three causes to complete his land. Again, because the intent differs, the sutra text is not identical. [Dao]sheng says: Erecting a palace is a metaphor for bringing sentient beings to fruition. An empty plot of land is an unhindered place, a metaphor for taking what is free of defilement; defilement is hindrance.
