成唯識論演祕 3.221

3.221

略為二釋。一云如因第八緣自三境，但相無質。心所杖八相為質緣，或所更互託為質起，故不可言本質是同名為同一。由此應言相名行相，行相相似，名同所緣。二云疏錯，應云然唯第二無初解者，餘言同前。

There are briefly two interpretations. The first says: Just as in the causal stage the eighth consciousness takes its own three spheres as objects, having only images without external substances. The mental factors rely on the image of the eighth as their external substance to take as an object, or they mutually rely on one another as external substances to arise; therefore one cannot say that having the same external substance is called having an identical [sphere]. For this reason, one should say that the image is called the cognitive aspect, and because the cognitive aspects are similar, it is called having an identical object. The second says: The Commentary is in error; it should say: "However, only according to the second, without the first explanation...", with the rest of the words being the same as before.
