Tammy Hatherill’s comment, down near the bottom, was insightful I thought. She says, "Tarot is a healing, because all sorts of information come up in a tarot reading. It's information that people need to know, not necessarily what they want to know..." This resonates somewhat with Jung’s preface to the I Ching -
In the exploration of the unconscious we come upon very strange things, from which a rationalist turns away with horror, claiming afterward that he did not see anything. The irrational fullness of life has taught me never to discard anything, even when it goes against all our theories (so short-lived at best) or otherwise admits of no immediate explanation. It is of course disquieting, and one is not certain whether the compass is pointing true or not; but security, certitude, and peace do not lead to discoveries.
