I found it here originally, they still seem to be there if you're happy testing the waters before buying: http://en.bookfi.org/
If you've read summaries you could go straight to the last book 'The Luminous Ground'. It's the shortest at 300ish pages and I think the most relevant to you, on spiritual aspects of form/ building/ art, with plenty of examples from world religions inc. Medieval Catholicism. It's kind of a deist/ perennialist argument based on the structures of matter.
Well, I read that whole blog series using scenes in The Office to illustrate the three-tier theory of organizational and individual psychology. It made me realize how arrested development has limited me, and it has also made me realize how I have always had a sense of existential emptiness. I also had a lot of Loser qualities that made me judge myself and others by non-mainstream standard. I have yet to make sociopathy a joyful activity, though, partly due to my incompetence and my profound sense that moral failure on the part of everyone promotes strife that is ultimately futile. The lack of an iron curtain covering the Wizard of Oz means that corruption at the top promotes corruption at the bottom eventually.
