Great little book - and obviously very visual, which is good given the importance of the 'symbolic' in the subject matter. Thin, as one reviewer, says, but produced to a high quality and very very dense - not an easy book to read through in one go! Plenty of material to go back to, and no right or wrong answers (which i find refreshing in this day of "self-help"/conspiracy etc. books that purport to know it all), but a work of great scholarship that provides an 'abstract' of source material, and invites us to share in the mystery.
