In plain words
Only non-duality is real. The duality that seems to be in it is not real — it has been laid over it, the way silver appears on a piece of mother-of-pearl, the way water shimmers in a mirage.
Close to the Sanskrit
Non-duality alone is real; in that, duality is not real — it is superimposed: like silver on mother-of-pearl, like the shimmer of water in a mirage.
