成唯識論演祕 2.726

2.726

問：既云所變，八識幾是能變識耶？傳有三釋：一云，唯除第六顯餘七識，第六所變即親所緣，下文別說起自心相執為法故。二云：通八，雖第六變是親所緣。初文通說，下方別說親所緣緣故亦無失。三云：唯顯第六意識，由是即說唯親所緣。既是親緣故，蘊、處、界唯是有漏，同前取蘊，但開合異。有義斷云：言識所變即親所緣，如何復言起自心相？由此但依《疏》解為正。

Question: Since it says "transformed," among the eight consciousnesses, how many are the transforming consciousnesses? Traditionally there are three explanations: The first says: Excluding only the sixth, it shows the remaining seven consciousnesses; what is transformed by the sixth is the direct object (pratyakṣālambana), because the text below separately states that it gives rise to its own mental image and grasps it as a dharma. The second says: It applies to all eight; although what is transformed by the sixth is the direct object, the opening text speaks generally, and only below does it distinguish the direct objective condition, so there is also no fault. The third says: It reveals only the sixth mental consciousness, and is thereby said to be solely the direct object. Since it is the direct object, the aggregates, sensory bases, and elements are solely defiled, identical with the previously mentioned aggregates of grasping, differing only in division and combination. An opinion determines: If it is what is transformed by consciousness, it is the direct object; how could it further say that it gives rise to its own mental image? Therefore, only following the explanation in the Commentary is correct.
