楞伽阿跋多羅寶經註解 2.287

2.287

此四喻，初喻妄想自性。言修行事者，如禪有十種一切處，謂青黃赤白等皆遍一切，其境本一，以心想故有種種現，妄想之相亦復如是。次種種翳下，喻緣起自性，翳本無色，妄見色現，故無色非色之實，緣起不覺亦復然也。又鍊真金、空無翳二喻，皆喻成自性也。言無彼妄想緣起二種自性，則如金之無垢、空之無翳，故云「妄想淨亦然」也。

These four analogies: the first illustrates the vikalpa-svabhāva. In speaking of “the practices of cultivation,” it is like meditation possessing the ten kṛtsnāyatanas, meaning that blue, yellow, red, white, and so on all pervade everywhere; their object is originally one, yet because of the mind's ideation, various appearances manifest. The marks of vikalpa are also like this. Next, from “various cataracts” downward, it illustrates the paratantra-svabhāva: a cataract originally has no color, but through delusion one sees colors appear; hence there is no reality of color or non-color. The unawareness of paratantra is also like this. Furthermore, the two analogies of refining genuine gold and empty space free from cataracts both illustrate the pariniṣpanna-svabhāva. This means that when free of those two svabhāvas of vikalpa and paratantra, it is like gold without taints, or space without cataracts; hence it says, “the purification of vikalpa is also like this.”
