Funny you should ask . . . I have it open and I was working with it as I idly browse the forum.
I have been working with the book and the exercises since May. This summer has seen the most important, profound, and defining personal tarot work I have ever done.
The exercises are a set of Majors-only reading that flow in order and allow you to take a great look at your personal shadow character. Each spread is a five-card majors only spread. The initial spread is an overview on five different areas. Then each spread after that focuses on one area of that original spread. The focus is on revealing and working to find a healthy way of integrating your shadow aspects.
Christine Jette loads the book with loads of essential and helpful information that do far more than augment an understanding of a spread. She gives in her book many supplementary ideas in how to prepare and safely engage in what can be very personal and revealing exercises.
I would strongly encourage getting the book if just for the four spreads but the nature of the work is so potential powerful that the other information makes it more guide and workbook than simple text. The book does seem to have pagan/wicca slant but even though that is not my journey, it is still very practical and insightful.
I have found that this process really helped me bond with my personal deck, also I believe that this initial time through the book has been great and helped me address many different issues current in my life. I also feel that there is something more or deeper that still is yet to be discovered but understand that this first trip through is preparation for when I am ready to start dealing with my more deeper and darker issues.
Couldn't recommend this book enough and is routinely found at a reasonable price as it has been eight years since it was released. So not for the weak or timid but very, very worth the price of the book to learn these techniques that will help me improve myself and work with my tarot clients.
On a side note, as I am completing this journey I am very interested in Jette's Tarot for the Healing Heart and how that it would complement and augment the lessons in this book.
Hope this helps.
