It is a good one as well, very dense. In it JBP explores more deeply psychoanalytic ideas from C.G. Jung, E. Neumann and others. Definitely requires more focus, the concepts presented are varied and it is closer to an academic textbook than to a consumer book of the self help type. If you like 12RFL, comfortable with intellectual stuff and want a deep dive into the mediation process between chaos and order, I suggest that one as well.
