成唯識論述記 1.420

1.420

述曰：自下第四、第五，以體一分，例餘一分。量云：薩埵等三，一分轉變成法之時，餘之一分亦應轉變；此體即是彼薩埵等，體無別故。或云：許體遍一切故，如一分轉變者。此二比量，一、體無別因；二、遍一切因。若許一分變，餘一分亦變，即此三事無不變時，便違宗失。彼計此處變為山水，彼處即不變，自性之體仍遍一切故。

The Commentary states: Below are the fourth and fifth [refutations], using one part of the essence as an analogy for the remaining part. The syllogism is: When one part of the three [entities], sattva and the rest, transforms into a principle, the remaining part should also transform; because this essence is identical to that of sattva and the rest, and their essence is without distinction. Or it may be stated: because you accept that their essence is omnipresent; like the part that transforms. These two inferences have: first, the reason "because the essence is without distinction"; second, the reason "because of being omnipresent." If one accepts that when one part transforms, the other part also transforms, then these three entities would never have a time when they do not transform, incurring the fault of contradicting their own school. For they posit that transforming into mountains and waters occurs here, while over there they do not transform, since the essence of prakṛti is still omnipresent.
