One recurring theme in the book is the interesting string of coincidences that starts to follow you around once you start to enter the practice of magick, of "self-induced brain change" as he puts it. RAW is carefully agnostic on whether the perceived coincidences stem from psychology of perception, parapsychology, quantum physics, a holographic universe, some synchronicity beyond our ken, or what.
One of his favorites is the "23 connection". I've always been more of a "Law of Fives" man myself (remember, the harder you look, the more you'll see the Law of Fives manifest), but I've seen 23 spring up a few times.
Like when, on Saturday, just a few days after finishing re-reading Cosmic Trigger, 23s still dancing in my head, I see one of these movie posters for "The Number 23" in a bus stop shelter as Cathy was driving us to the Metro stop to go down to D.C. for the anti-war march.
So, what does it mean, we immediately want to ask, given a coincidence like that. I've pretty much eliminated parapsychology from my list of options to consider, given the repeated failures of "psychics" to perform under controlled conditions; and most occult and mystical attempts to invoke quantum theory are straight-up gobbledygook. (I'm looking at you, Deepak Chopra!) But other than that: psychology of perception, a holographic universe, some synchronicity beyond our ken, I don't know.
And, as one Zen Master put it, "don't know is closest to it". Or, as some goofball once said in response, "Don't know? I don't know?! Third base!"
