I ordered the Jodorowsky book from amazon.ca about a month ago, and I'm about two thirds through it now.
As I posted on a
thread in the Marseilles seciton, I was somewhat disconcerted by a perceived authoritarianism I found in Jodorowsky's book. This impression has not changed much as I read deeper. Jodorowsky's approach is also steeped in Jungian psychology, and has something of the flavour of old-time theosophy in it as well, and that sort of thing is a bit more diffuse than I would have liked. Some of Jodorowsky's divinatory meanings strike me as a bit impractical; he assigns a core meaning of "Nirvana" to the 8 of Swords, for example --- what are you going to do with that in a reading?
Still, he presents some interesting ideas. I like his notion that in each of the pip cards, one card among the four suits will stand out as somehow "different" in each rank. Since I do put a fair amount of stock in Gareth Knight's approach involving visualized conversations with the several characters, the monologues Jodorowsky gives to each of the trumps and court cards have been the most enjoyable feature of the book for me.
If you are going to try to read one French book on the Tarot de Marseille, I'd strongly recommend Carole Sédillot's
Ombres et lumières du tarot over this one. This and Jodorowsky's are the two I've tried; I've also read Joseph Maxwell in English. Sédillot's approach to a very different tradition is encyclopedic, precise, and practical; Jodorowsky's is much more theoretical and at times too metaphysical/psychological. For people from the English speaking traditions, all of this is going to be quite new to you.
If the Camoin-Jodorowsky deck is your favourite TdM, the Jodorowsky book is the one you need to unlock all of the mysteries Camoin and Jodorowsky say they have uncovered. I believe the Rodes-Sanchez deck follows Camoin and Jodorowsky to some extent; not sure what the politics behind all that are, and don't much care.
