The Spirit of the Tarot
The Search for God's Picturebook

Tarot is valuable quite apart from whether it has any power to predict the future.  Indeed, whether the tarot can predict the future is not the most important question to ask. What makes tarot valuable lies elsewhere. Tarot is a rich set of symbols that allows us ample room for thinking about our lives in creative ways.  And that, it seems to me, is saying quite a bit.
