If you're referring to the book by Echols, Mueller and Thomson, I have that one! It's pretty good, depending on what you're looking for. I've kind of been using it for meditation purposes.
The biggest chunk of the book consists of descriptions of each card, small illustrations from three different decks (RWS, Morgan-Greer and Aquarian), discussion of the sybolism present in each card/deck and some thoughts on meditations.
Briefly, yesterday I was studying the 8 of Cups:
(each section starts off with few paragraphs written from the perspective of the card!)
I know it's time for me to make a move. I have been fortunate thus far. I would not change anything of the past, but I feel a need to leave behind conventional things and try something new... there's more, but I won't type it all.
then the key phrase: taking time for me
descriptions of the cards, etc.
analysis of symbolism and meanings, etc.
"shadow side" of card includes: failing to allow time to study and introspection; emotional withdrawal; etc. etc.
meditations:
•become aware of what it is you want ot leave or to avoid
•consider how your past attitudes and action have brought you to your present situation. can you allow yourself the soul-searching necessary to make new plans?
•identify any regrets or feelings of loss you may have and consider how you can live your life differently from this point on.
•look for ways to incorporate spiritual exercise into your daily life...
anyway, hope that helps! if you have more questions, ask away!
