The World is (in) Real(ity Self).

The word illusion is misunderstood. Illusion does not mean unreal for there is only the real as in (el) real as in (the) self. Simplified. Illusion means 'self (i) desires'. Now what does self desire? Self desires not to be alone. Hence why the word manifests itself as the world. Both are self naturally. The world is self not wanting to be by itself. The world is self embracing itself. The world is self experiencing as differentiated so to be able to love itself. In nuce. It's all good.
