" We talked a little set theory, and then I asked him my last question: “What causes the illusion of the passage of time?”
Gödel spoke not directly to this question, but to the question of what my question meant — that is, why anyone would even believe that there is a perceived passage of time at all.
He went on to relate the getting rid of belief in the passage of time to the struggle to experience the One Mind of mysticism. Finally he said this: “The illusion of the passage of time arises from confusing the given with the real. Passage of time arises because we think of occupying different realities. In fact, we occupy only different givens. There is only one reality. "
