成唯識論演祕 3.372

3.372

詳曰：如菩薩等，變身為魚、地、海金、酪，下界有情得受不耶？若不受者，變之何益？若許用者，有情第八豈不緣彼？不緣而受，非唯識故。故知因他通力而引能變異地身器等也，即彼扶塵名為身也，魚、金、酪等非欲界故。設若救云：有情六識託菩薩等所變米等，以為本質變而乃用，亦如上眼緣下三災，託下第八所變為質。此亦不然，縱緣自六所變之者，第八從本言由通力，亦何傷也？與餘常時，境不同故。前云上眼，託下第八。由上第八，不得緣下。所以然者，若上第八，自變下災，麁細既隔，於彼無用，若杖下八所變之災為質方變，變復何用？又非定通之所引故。由斯不變，若變魚、米而有用故，復通力引何得相例？若麁細別，不許變者，即餘六識亦應不緣，麁細隔故。

Detailed analysis: For example, when bodhisattvas and others transform their bodies into fish, earth, sea, gold, or curds, do sentient beings of the lower realm receive and use them or not? If they do not receive and use them, what benefit is there in transforming them? If you grant that they use them, how could the eighth [consciousness] of those sentient beings not take them as objects? If they were to use them without taking them as objects, that would not be vijñapti-mātra. Therefore, we know that, induced by the power of another's supernormal power, one is able to transform a body, vessel, and so forth of a different plane; that very supporting matter is called 'body,' for fish, gold, curds, and the like are not of the desire realm. If, in defense, it is said that the six consciousnesses of sentient beings rely on the rice and the like transformed by the bodhisattva and others as the mūla-dharmin, transforming it before using it—just as the upper [realm's] eye cognizes the three disasters below by relying on what is transformed by the lower [realm's] eighth as its mūla-dharmin—this also is not so. Even if it takes what is transformed by one's own six consciousnesses as its object, if the eighth consciousness is said from the root to be 'due to the power of supernormal powers,' what harm is there in that? For it is not the same object as in other, ordinary times. Earlier it was said that the upper eye relies on the lower eighth. Because the upper eighth cannot cognize below. Why is this so? If the upper eighth were to transform the lower disasters on its own, since the coarse and the subtle are separated, it would have no utility for it; if it were to rely on the disasters transformed by the lower eighth as the mūla-dharmin before transforming, what utility would there be in transforming again? Furthermore, it is not induced by meditative concentration or supernormal powers. Therefore it does not transform them. If transforming into fish and rice has utility, and is furthermore induced by the power of supernormal powers, how can the two cases be compared? If on account of the distinction between coarse and subtle it were not permitted to transform them, then the remaining six consciousnesses likewise should not cognize them, since coarse and subtle are separated.
