成唯識論述記 5.793

5.793

述曰：義准不善，返善亦爾，非必十法俱故，望聚為論。不善中，十唯不善故，謂嗔及忿等七，除諂、誑、憍，取無慚、愧，故成十也。

The Commentary states: By principle, unwholesome can be deduced by reversing wholesome, and it is also like this: because it is not necessary that all ten dharmas be associated, it is discussed in view of the group. Among the unwholesome, ten are exclusively unwholesome: namely, anger and the seven from wrath onwards, excluding deceit, fraud, and arrogance, and taking shamelessness and consciencelessness; thus making ten.
