Boring, wordy and not really about tarot? Well, yeah, in the sense that it's a long, complex book about so much more that the Tarot that it's like a bomb going off inside you when you start to follow where it's going. It took me several abortive attempts over half a decade to get past the first couple of chapters. But eventually I took the time to sit down and read one a night for three weeks. I'm really glad I did.
It's heady stuff, strong wine, but not deliberately intoxicating as so many "spiritual" books are. A date rape drug it's not. The anonymous author was once involved with Steiner but became a Catholic, and this is a deeply, devoutly Catholic book. It'll draw you, if you care to go, more deeply into the Christian-Hermetic tradition than anything else will, I think -- even Rene Guenon or Fulcanelli, who are not to be sniffed at themselves.
"The purpose of these letters," according to the author, "will be to incarnate into this tradition, i.e. to become an organic part of it, and in this way to contribute support to it... Their aim is not only to revive the tradition in the twentieth century but also, and above all, to immerse the reader (or rather the Unknown Friend) in this current -- be it temporarily or for ever."
It couldn't be less about divination or self-affirmation or transpersonal psychology. In fact, it sits far more comfortably alongside the work of such fine, authentic 20th century theologians as Henri de Lubac and von Balthasar (who wrote the preface to the German edition) or, say, Pavel Florensky than it does on the occult shelf where it's usually found. I love this book. It was worth writing and worth reading in a way that sets it apart from all but the tiniest few.
