唯識二十論述記 1.56

1.56

述曰：自下第二，簡擇「唯」言。論所引經，說唯心者，言雖唯心，意亦兼說唯諸心所。以唯有心所，無實所取故。

The Commentary states: Below is the second [part], clarifying the word "only". When the sūtra cited in the treatise speaks of "mind-only," although the words say only mind, the intention also includes solely the mental factors. For there are only mental factors, and no real grasped objects.
