 These verses emphasize the crystalline, internal structure to the three natures. “What appears” is one nature (the dependent), whereas “how it appears” is the fabricated. “The eternal non-existence of the appearance as it appears” is the perfected. These are ways of talking of the same entity, or event, from different perspectives. Also evident here is the crucial Yogācāra concept of “duality.” The fabricated is said to appear as a “dual self,” whereas reality (dharmatā) is nondual. Since, as we have seen above, Vasubandhu believes in the selflessness of all dharmas, the “dual self” is the false appearance of a self that is attributed to any entity. Things and selves mistakenly appear “dual.” What does this mean?
