瑜伽論記 19.272

19.272

備云：相名二事約處以辨內外，分別正智同是有情法故。且約所緣境判其內外，內外者名之為內緣，外身者名之為外。

Bei says: The two entities of signs and names are distinguished as internal and external according to their locus; discrimination and correct gnosis are both sentient phenomena, so their being internal or external is distinguished tentatively on the basis of their objective spheres: [taking internal entities] is called taking the internal as an objective support; taking the external body is called external.
