Query: Interesting area not usually looked at in PKD's work

Taking a look at the religious aspects of PKD's work shines an interesting pink beam of light on things. The knowledge base of the author across a wide variety of religions allows him to put forth many questions and answers about how/why/meaning of many books from PKD and what greater concerns of higher level he had. PKD used religion in books as varied as MITHC, DADOES to later books such as Divine Invasion and Valis. This pulling together into one source makes it easy to understand how from greek to christion to eastern religions they all fit into his pantheon of work. I'd also look into combining this with a couple of other good books, notably Philip K. Dick: Exhilaration and Terror of the Postmodern by Christopher Palmer and The Shifting Realities of Philip K. Dick by Lawrence Sutin. All nicely written as well. Pick up the Pink Beams of Light..., and it will shed some illumination on this neglected aspect of PKD's writing.
