 Fazang explains the relation between these two aspects of One Mind by positing a distinction between Suchness and Ignorance. Suchness is the true nature of reality. Fazang posits that Suchness has two aspects, one unchanging, the other accompanying change. Suchness as unchanging is calm and quiescent. Suchness as accompanying change, by contrast, is dynamic, embedded within the ebb and flow of conditioned dharmas. Because Suchness is available for encounter only to witnessing consciousness that lacks a sense of self, Fazang characterizes it as empty. Ignorance, by contrast, is that which initiates dukkha. Fazang posits that it, too, has two aspects. As empty, Ignorance renders its results illusory. As actively functioning and completing affairs, it perfumes conditioned dharmas with hindrances and defilements. Because it is responsible for the appearance of illusory objects, Fazang characterizes this aspect as existing.
