成唯識論了義燈 2.10

2.10

疏云：其實亦有非無本質是俱生故。故此所言五取蘊等，皆起影像；言亦者，以相分亦本質，無有無相計為我者，故言起自心相；亦有非無本質者。故言緣五取蘊。

The commentary says: "In reality, there also is, and is not without, a fundamental basis (mūlālambana), because it is innate." Therefore, what is spoken of here as the five grasping aggregates and so forth all give rise to mental representations (pratibimba); the word "also" means that the objective aspect (nimittabhāga) is also the fundamental basis; there is no one who, without an image, calculates it to be a self, which is why it says "giving rise to an image of one's own mind; there also is, and is not without, a fundamental basis." Therefore it says "taking the five grasping aggregates as object."
