瑜伽論記 4.245

4.245

內無色想，觀外諸色者，彼小乘說內已伏除色想名內無色想，唯觀外境名觀外色。今此論已依無色定離色界染名內無色想，即此諸色已出染故名之為外，觀此為境名觀外色。上二言觀者，於諸色中為變化自在故，意解思惟顯示彼想故。

"Internally without the notion of form, one contemplates external forms": That Hīnayāna [school] says that internally having suppressed and eliminated the notion of form is called "internally without the notion of form," and contemplating only external objects is called "contemplating external forms." Now, this treatise explains that having relied on the formless absorptions to abandon defilement of the form realm is called "internally without the notion of form," and because these very forms have transcended defilement, they are called "external"; contemplating these as objects is called "contemplating external forms." The word "contemplates" in the above two refers to conceptualizing and mentally reflecting so as to manifest those notions, for the sake of mastery in miraculous transformation among forms.
