There are only two titles of Jung's I know of that were meant for general consumption: _Man and His Symbols_ and _Memories, Dreams, Reflections_. The rest, most of which are part of the 20-volume Bollingen series, are too involved and technical.
Lest the reader be misled _Man and His Symbols_ is an anthology of essays by several authors, namely and in their order of appearance, Carl Jung, Joseph Hendersen, Marie-Louise von Franz, Aniela Jaffe, and Jolande Jacobi. All the co-contributors are Jungian analysts themselves and so are versed in the subjects they cover. Jung picked them himself and supervised the work until his death in 1961, after which von Franz took over. Perhaps not by accident Jung finished his own essay just 10 days before his demise. His essay (just over 90 pages out of the 400 or so pages) touches, naturally, on the unconscious, the very crucial subject of dreams, the archetypes, extraversion/introversion, religion, good and evil, among other topics. Given the scope, this essay of his offers a sort of synopsis of his worldview and life's work, perhaps one of the best summaries since it was his last published piece.
Amongst Jung's books that I've read, his essay in this anthology is by far one of the most engrossing. Unfortunately I have to eke out a living like most of you so I can only savor it in installments. Of course I highly recommend this volume if only to whet your appetite for Jung's psychology, a psychology that has not only served me well, but continues to fascinate me, a psychology that is faithful to its roots--a true logos of the psyche.
