Everything that is solid, spatial & global only seems to exist, but in truth, these are just our own sensations.
When we see a wide world before us, we don’t see it in reality, but only within ourselves. In other words, there is a sort of a photographic machine in our hindbrain, which portrays everything that appears to us and nothing outside of us. – Baal HaSulam, “Preface to the Book of Zohar,” Item 34
