Read this as a follow up to Atom and Archetype, the collection of letters between the Nobel laureate physicist and the pioneering analytical psychologist. You could read it before the letters and have a deeper sense of the context, but I think I'm glad I got the raw material first. There's some solid biographical background, but the core is in the way Lindorff (a Jungian analyst) works with Pauli's dreams. I picked up some things of use in my own work, most important involving the way that people from our "real lives" serve symbolic functions in our dreams. Mostly for those who are already involved in the conversations, but not a bad introduction.
