I recommend reading this book as an excellent way to connect or reconnect with Jung and his ideas. Von Franz is the most skillful and eloquent translator of Jung's ideas, and she explains them with an ease that Jung himself never seems to have had.
Most fascinating here are the explorations of Active Imagination and the interpretations of dreams. Particularly on the topic of A.I., von Franz elucidates the method of psychic-exploration in a way that will inspire and encourage. She explains Jung's thinking that this is indeed a very real process, and the journeys undertaken are as real as any others in the fully conscious world, and the places we visit exist independently, at least as any other places we can go. As a meditation, A.I. does happen "to you," except that "you" are somehow a part of it symbolically at the same time. Regarding the interpretation of dreams, the author cites Jung as saying that these experiences are not easily interpreted one way, and that we may do better not solidifying them into any particular interpretation at all. This point is a good reminder, explained well.
The lengthy exposition of relationships between the "No. 1" and "No. 2" personalities--the lives of the consciousness and the vast unconscious being--illuminate the teaching that "No. 1" should always be first, with "No. 2" enriching and deepening the experience of the conscious person. This is an important point that may be--and must not be--overlooked in the Search.
All explanations of this book seem to fall short. It seems almost a must-read for someone exploring and practicing Jungian processes. It is inspiring, illuminating, and so distilled and easy to read compared to the texts of Jung himself.
