I have also seen some very strange things in the words of some contemporary kabbalists who explain things deeply. They say that all of existence is only an illusion and appearance, and does not truly exist. This is to say that the ein sof didn't change at all in itself and its necessary true existence and it is now still exactly the same as it was before creation, and there is no space empty of Him, as is known (see Nefesh Ha-Chaim Shaar 3).
