成唯識論演祕 1.764

有義：九句之中，隨除何句以為宗、因？言非實等，非顯多量，所以者何？且如初宗言德等者，除無說句並皆等不，若不等不盡，因便不定；若言等者，餘皆所等，即一宗、因已能成立所等八句，非離識有，更餘為宗，犯相扶失。前已成故，由此初量總成八句，後別立一總成二量。

One interpretation says: Among the nine categories, whichever category is excluded to form the proposition and reason, saying "not substance" and so on does not indicate multiple inferences. Why is that? Take the initial proposition stating qualities and the like: does it include all except the non-predicable category? If it does not include them all exhaustively, the reason becomes inconclusive; if one says it does include them, then the rest are all included, so that a single proposition and reason already establishes the eight included categories as not existing apart from consciousness. Taking others as the proposition would commit the fallacy of proving what is already accepted, since it was established earlier. Thus, the initial inference comprehensively establishes eight categories, and subsequently another is established separately, yielding two inferences in total.
