瑜伽論記 4.246

4.246

解脫者，謂能解脫變化障故，依對法說：內謂內身，已依無色定伏除見者色想名內無色，與此不同。此中備云：未離欲時自見名內色，他見非情名為外。然已得離欲界欲貪，在色界定內都觀於色界欲界之色，故自他色合名為外色。泰云：於二界色之上色欲未離名內有色，若於此內身已得離欲時即說內身名曰外色，無色欲故，不唯觀身外色名外。

"Liberation" means being able to be liberated from hindrances to miraculous transformation. According to the Abhidharmasamuccaya: "internally" means the internal body; having relied on the formless absorptions to suppress and eliminate the seer's notion of form is called "internally without form"—which differs from this. Here, Bei says: When one has not yet abandoned desire, seeing oneself is called "internal form," and seeing others or inanimate matter is called "external." However, having already attained liberation from the desire and greed of the desire realm, when in the form-realm concentration, one universally contemplates the forms of both the form realm and the desire realm; thus self-form and other-form are collectively called "external forms." Tai says: The desire for form having not yet been abandoned in relation to the forms of the two realms is called "internally having form." If one has already attained liberation from desire in relation to this internal body, then this internal body itself is called "external forms" because there is no desire for form, and it is not only contemplating forms outside the body that is called "external."
