Not Two, Not One

To the author of the Hsin Hsin Ming, the relative is merely as aspect or "appearance" of the one inseparable Reality (or Absolute). But: do not suppose that the Absolute has some sort of existence which is independent of all else that it is; it is not a state, condition or entity in its own right. As the sutras say of it: "Not two, not one." In truth, the Absolute cannot even be conceptualized as the "one thing."
