What is The Red Book for analytical psychology?

The Red Book enters the field of analytical psychology belatedly, yet presents itself as a foundational text. In this paper, I try to estimate how it will affect the field and to reflect on how it can be used by contemporary readers and clinicians. Jung's own works remain the baseline for theorizing and teaching the fundamental perspectives of analytical psychology, and yet the field has grown far beyond his own contributions. Is this late inheritance of central value or only of peripheral interest for the field? It can be used in various ways and certainly shows many interesting features that link it to Jung's later works, but does it detract or does it add? And if it adds, what does it add? In The Red Book, Jung is speaking to us from the grave. What is he saying? In this paper, I explore how it can be used as an inspirational text for keeping alive the spirit of the ancestors in the field and for linking the present to the deep past.
