In plain words
Duality has no reality of its own, yet it cannot be sheer nonexistence. It is not real, because it is sublated; it is not unreal, because it appears directly.
Close to the Sanskrit
Duality has no existence by itself, while what is unreal has no existence at all. Because it is sublated, duality is not real; because it appears directly, it is not unreal.
