I used a little Rosicrucian material in this volume; there'll be more in a future volume, though right now what I'm doing is going through reams of academic papers on the archeology of temples, trying to put together as much data as possible on the technical details of temple design and use.

My main Rosicrucian involvement is in the Societas Rosicruciana in America (SRIA), which has a refreshingly openminded attitude toward the old traditions of secrecy; the only things that are private are the correspondence lessons and initiation rituals. The material on ancient traditions is publicly available, though cryptic.
