2.62

As for "not as it truly is" and so forth: If one knows that the true body is real and the responsive body is illusory, and further understands that marks are themselves without marks—which is termed the true body—and that being without marks is itself marks—which is termed the responsive body—to see thus is called "seeing as it truly is." Therefore the *Avataṃsaka* says: "Seeing reality in the real, / and seeing unreality in the unreal: / one who understands the characteristics of phenomena thus / is called a Buddha." If it is not thus, it is called "not seeing as it truly is."
