। - ॥ २३७ ॥
In plain words
So the world isn't really separate from the Supreme Self at all — that sense of separateness is simply false, the way a quality only seems separate from the thing it belongs to. What independent reality could a superimposition ever have? It's only the underlying ground itself, appearing that way through a mistake.
Close to the Sanskrit
Therefore the world does not exist separately from the Supreme Self; the cognition of separateness, however, is false, like [that of] a quality [distinct from its substance]. What real existence does a superimposed [thing] have? [It is only] the substratum appearing thus, through delusion.
