In plain words
Grant that duality is unreal: it comes up only out of the mind's own construction, exactly like what you see in a dream. Grant it also because duality was not there before it appeared, and because 'it exists', 'it does not exist', and the rest are labels thought lays onto it.
Close to the Sanskrit
Because of its arising from mental construction, the unreality of duality is to be admitted, like a dream-object; and because of its non-existence beforehand, and because of the imagining of existence, non-existence, and the rest.
