Picked up Mysticism in the 21st Century (Monette, Shoup) after seeing the Insider video of an FBI undercover agent talking about his experience in an accelerationist (in the white supremacist sense) group with esoteric touches. Went down a rabbit hole and eventually came across this treasure.
Aside from the fascinating detail it adds to that topic, I also look forward to seeing the chapters on other spiritual-adjacent stuff.
