Next on the to-be-read pile: Jung's Map of the Soul, by Murray Stein.
It's a fairly good synthesis of many of Jung's concepts..
However, I find reading summaries of Jung to be quite dry compared to reading the man himself. The thing you have to remember about Jung is that he was an intuitive genius. His own writing reflects that; if you also have an intuitive mind, you find yourself getting immersed in the
flow of his work, and it is the flow, the
pattern, of his thinking that does more to explain the concepts than the actual words he uses. Often, he backtracks and ends up in intellectual cul-de-sacs, but if you can stick with him, there's a real "drama" to his writing.
When someone else tries to explain his concepts, especially if they are more concrete in their thinking, it can easily become very dull, and list-like. Stein's book explains most of the concepts quite adequately... but without the vivid inspiration and drama you can read between the lines in Jung's own writing. It's more understandable, for a lot of readers, as a result... but not as engaging. I prefer reading Jung directly.
Which you prefer probably reflects how you prefer to process information (Jung would probably argue that it's a function of whether you are rational or irrational in temperament.

). If you haven't already, read Jung's autobiography (Memories, Dreams, Reflections) to get an idea of his own writing style, and so whether you want to try reading his work in his own words.
