Celestine Books
I'll describe the german books here, because they are the ones I know.
But since the Celestine Prophecy was translated to many languages, I'm sure you will get most of these books in your language as well - at least in english.
Everyone who wants to work with the first nine Insights, I can recommend the book "The Celestine Prophecy: An Experiential Guide". (For the Germans I could recommend the Book of Celestine in this place, which contains the novel and the guide in one, but I couldn't find it in english, sorry.) And there is an audio book "The Celestine Prophecy" as well - for these who prefer hearing to reading .
For the second book "The Tenth Insight", too, there is a manual named "Holding the Vision: An Experiential Guide" to have a good deepening in the topics. An audio book isn't published though.
Book three and four - "The Secret of Shambala" and "The Twelfth Insight" -, don't come along with manuals this far, but for the last Insight we have an audio book again.
Then there is a very nice book review in German from Peter Handl named "Celestine - Der Aufstieg des Adlers zur Sonne" (Celestine - Rise of the Eagle to the Sun) to get from Johann Kössner. He doesn't just explain all Insights but refers to the Mayan Calender as well. Even those who doesn't know about the topics of the Mayan Calender will be fine with this book.
You can download the book at Kössners Homepage (along with other very interesting books; in German though), for a voluntary energy compensation about 7,- €.
