+ Direct perfect enlightenment [with regard to] all aspects,
+ and abandonment of the stains along with their imprints
+ [are called] buddha and nirvana respectively.
+ In truth, these are not two different things.
+ —Arya Maitreya
+
+All aspects of the knowable—all absolute and relative phenomena—are
+directly known. Through this knowledge one is immediately and perfectly
+enlightened. This is the aspect of realization. All the adventitious
+defilements—the two veils along with their remaining imprints—are
+abandoned without any exception. This is the aspect of abandonment. These
+two qualities have been led to ultimate perfection. They are therefore named
+"perfect buddha" ["perfectly awakened and expanded"] from the
+viewpoint of the former aspect, and "nirvana" ["gone beyond any torment
+and pain"] from the viewpoint of the latter aspect. These two aspects are
+contained in one and the same meaning, the meaning of the tathagatagarbha,
+whereas a difference only lies in the convention of the different terms. In
+the sense of the absolute field of experience of the noble ones’ primordial
+wisdom the qualities of realization and abandonment are therefore completely
+inseparable and do not exist as two different things.
