When we seek comprehension of that aspect of the Overself where there is no universe at all, no activity, no ideation, we seem to enter a great void, an utter no-thingness. The "I" cannot breathe in this rarefied atmosphere. And yet it would be the supreme illusion in a world of illusions to regard this void as the abode of unreality.
No object in the universe corresponds to the Overself; therefore we are forced to term it "The Void," but the existence of all objects is only explained by its own.
We may fittingly compare the Overself with any catalytic agent of chemistry which, unaltered itself, activates other substances by its presence. We may carry the comparison further and point out that just as the catalyst is ultimately a product of the same primal stuff as these substances, however different they appear to be, so the thoughts and things whose play constitutes the universe are ultimately of the same primal essence as the Overself.
