I came across this press release, announcing Robert Waxman’s new service: Kabbalah Lessons By Phone. His latest (and as far as I can tell only book is Kabbalah Simply Stated: A Conversation with the Rabbi, from 2004. I have not read it, but I am sure that my personal approach is different than his. He advocates that Kabbalah can and should be studied by everyone. For him Kabbalah provides a living, for me that would taint the experience/knowledge. Looking at his references I had the idea how interesting it would be to create a visual map of all (or the most-known) kabbalist masters. Representing teacher-student relationships, and familial ties too. One of these days… Till then his book will be added to the list of books on Kabbalah in English.
