成唯識論述記 8.290

8.290

述曰：因我執故，相分之中亦熏五蘊種，即名言熏習。由熏我執種，令自他別，故別立之也。初通六、七；後唯第六，其文易解，無勞更釋。

The Commentary states: Due to ātmagrāha, seeds of the five aggregates are also perfumed within the nimittabhāga, which is precisely nominal perfuming. Because the seeds of ātmagrāha are perfumed, self and other are differentiated, and hence they are established separately. The former extends to the sixth and seventh; the latter is solely the sixth. The text is easy to understand, so there is no need for further explanation.
