Our universe is a sort of hologram. VALIS/Zebra is trying to wake us up to this with illusions that demonstrate our phony world. Everything is flipped. What we expect to be grounded reality is fake and the nonsense is real. Dick’s writing has value in exposing this.
Dick is deep down the rabbit hole at this point. I often wonder what he would make of the conspiracy theories overwhelming our present time. He quotes a passage from Robert Anton Wilson’s 1977 Illuminati book Cosmic Trigger about Terence and Dennis McKenna’s book the Invisible Landscape. The McKennas, whose theories also borrowed from the I Ching, apparently believed two hyperuniverses interact to form the hologram of our universe. Every piece of a hologram contains information of the whole thing, so that concept would extend to our brains which would contain the whole of the universe. From their idea Dick extrapolates that the two hyperuniverses are the Black Iron Prison and the palm tree garden world which combine to create the hologram. One is signal and one is noise, and Christ is invading the Black Iron Prison world in order to destroy it.
Dick wonders why the omniscient entity doesn’t do more to alleviate undeserved suffering. Does it have limited power or knowledge, or is it operating in stealth mode to hide from its adversary? Dick concludes Christ is supplanting each suffering creature.
