成唯識論述記 1.451

1.451

述曰：此下第四，量云：又彼一一應有三體；體即相故；猶如本相。一一為量，或總為量。自下第五，總難大等，應無差別。

The Commentary states: From here down is the fourth [challenge]. The syllogism runs: Furthermore, each of them should have three substances; because the substance is identical with the marks; just like the original marks. One may form a syllogism for each one, or formulate a general syllogism. From here down is the fifth [challenge], broadly challenging mahat and so forth, [arguing that they] should lack differentiation.
