成唯識論演祕 3.234

3.234

論：文既說有心、心所，但緣境時無能緣相，故知唯就世俗以破諸師。皆言清辨「有相而無見」者，此不依宗，彼依世俗說唯識故。於世俗中雖有心、境，隱劣顯勝名唯識故。

The text of the Treatise already speaks of the existence of mind and mental factors, but merely states that when taking an object they lack the aspect capable of cognizing; therefore one knows that it refutes the various masters solely on the basis of conventional truth. As for the claim by all that Bhavya maintains "there are images but no vision": this does not rely on his school's tenets, for he expounds vijñapti-mātra on the basis of conventional truth. Because within conventional truth, although mind and objects both exist, concealing the inferior and revealing the superior is called vijñapti-mātra.
