I recommend Techgnosis by Erik Davis. It's like an updated Marshall McLuhan-like view into the meaning of the medium of modern information technology, but also with insights from ancient spirituality, esotericism, and psychedellia. I think it will connect the dots for a lot of people here, who might not otherwise encounter such a book.

I'm currently rereading Practical Idealism, or as idiots know it: "The Kalergi Plan to Destroy European Peoples." When you actually read it for yourself, you find that it's not a plan, but a prediction of the inevitable globalizing effects of the march of technology, as it compresses space and time. Though not explicitly esoteric or even spiritual; really this is a political white paper, when you read the book, you immediately sense how broad and deep a mind Kalergi had.

Prometheus and Atlas, as well as Closer Encounters, by Jason Reza Jorjani, are extremely /x/ and entertaining. Perfect for most people here, I think.

Though the title seems like something you probably would not read, if you like Manly P. Hall ideas at all, his Lectures of Ancient Philosophy (That's the book title.) were a great infusion of spirit for me when I read it.

Of course Kaplan's Sefer Yetzirah is required reading. IF you've already read it, read Steinsaltz's The Thirteen Petalled Rose.

And if you haven't, definitely read Flatland. It's a potent, fun little story.
