 According to He Yan, the solution to the mystery of Dao lies in recognizing its “completeness” or undifferentiated wholeness (quan). Precisely because the Dao is whole and complete, it is able to bring forth heaven and earth and the myriad creatures. For the same reason, in its undifferentiated fullness the Dao does not have any particular form, and as such cannot be pinned down conceptually and named. Even the term “Dao,” as the Laozi makes clear, is but a metaphor, a “forced” effort to reference a reality that is ultimately ineffable (Chapter 25). He Yan stresses the same point in his “Critical Discussion on the Nameless”: “The Dao [i.e., what the word ‘Dao’ seeks to point to] fundamentally has no name. Thus, Laozi said he could only force a name on it.”
