成唯識論述記 5.885

5.885

述曰：增上出生名根，故局；領納屬己名受，故通。領順、違境相，俱適身悅心，俱逼身迫心別也，故成三受。或身及心俱通適悅，俱逼迫也。

The Commentary states: Predominantly giving rise [to experience] is called a 'faculty', hence it is restricted; appropriating [an object] to oneself is called 'feeling', hence it is broad. Experiencing agreeable or disagreeable marks of objects, both comforting the body and gladdening the mind, or both tormenting the body and afflicting the mind, are distinct, and thus they constitute the three feelings. Alternatively, both body and mind are comfortably gladdened, or both are tormented and afflicted.
