成唯識論述記 9.335

9.335

述曰：前三非如，故言「亦」也。「真」簡有漏，有漏妄故；「如」簡無漏有為，彼體雖真，有生滅故。又，「真」簡初性，以妄執故；「如」簡依他，有生滅故。餘文可解。

The Commentary states: Since the preceding three are not tathatā, it says 'also'. 'True' excludes the contaminated, because the contaminated is illusory; 'suchness' excludes the uncontaminated conditioned, for although its substance is real, it entails arising and ceasing. Furthermore, 'true' excludes the first nature (parikalpita), because it is falsely grasped; 'suchness' excludes the other-dependent, because it entails arising and ceasing. The remaining text is easily understood.
