成唯識論述記 9.209

9.209

述曰：既出體已，次相攝者，七皆圓成攝，二智境故，謂實相、唯識、清淨三如根本智境，餘四真如後得緣故，此約增上。若談如體，一即七如，皆根本智境；約詮為論，七皆後得境。就約詮顯體，三、四境別，《顯揚》十六說與此同。

The Commentary states: Having already presented their essences, next is their mutual subsumption: all seven are subsumed under pariniṣpanna, because they are the domain of the two wisdoms. That is, the three tathatās of real characteristics, consciousness-only, and purity are the domain of fundamental wisdom, while the remaining four tathatās are cognitively conditioned by pṛṣṭhalabdha-jñāna; this is said from the viewpoint of predominance. If one speaks of the essence of tathatā, the one is precisely the seven tathatās, and all are the domain of fundamental wisdom; speaking from the standpoint of designation, all seven are the domain of pṛṣṭhalabdha-jñāna. In terms of revealing the essence through designation, the domains of the three and the four are distinct; fascicle 16 of the Prakaraṇāryavācā speaks in agreement with this.
