If you are of sound mind, stout heart, and good character, join CG Jung on the most intrepid and exhilarating journey imaginable: the journey to the centre of [a] man (that is if you can pry this book from the cloying grip of the academics and fundamentalists long enough to enjoy it for what it is and have the grace to let it be just that).
Be warned: it's tough going. You'll be exposed to primordial figures that may remind you of some of your own. You'll be thrown into a bewildering desert of early-twentieth century Swiss-protestant metaphysics (heavily spiced by Goethe, Nietzsche, and assorted mythologies). You'll see some of the complexes and neuroses of a great man exposed in all their horror and occasional hilarity. You'll marvel as big ideas find their first voice in a seemingly unwilling recipient. You may even share a little of the horror and pain as Jung fails to see the joke his own psyche is playing on him, or perhaps even occasionally misses the point? Best, you'll see many symbols and wonders of the soul that, whilst being all too familiar, remain elusive, beckoning, and truly awesome to behold. Yep, it's your basic esoteric hero's journey, writ large, for all to misinterpret.
The Red Book is a beautiful, rare, and unique artefact of someone else's process. It's almost like a travel book, documenting CG's personal and idiosyncratic journey across the great undiscovered country within. Like its author, it's a book that will draw out and amplify each reader's deep psychological prejudices (you may have already glimpsed some of mine). And it reveals that author and his psychology in a way his [or anyone else's] more conventional works never have.
If you love exploring the human soul, I'd be surprised if you didn't find this the most fascinating, exasperating and incredible book you've ever read, as I have. Enjoy, but be warned: you may loose some sleep over it!
PS: As befits the subject, the standard of scholarship and presentation of this book is exhaustive, exhausting, and without parallel.
