I am glad to hear about this book. He is in my lineage, and I have read a bit about him on the web, but not heard of his book.
Since you think so highly of it I will keep my eyes open for it.
As far as your other thread about it, I sometimes like to start at the solar plexus. It has been an intuitive thing for me, but I do think starting at the head is not always wise, for several reasons, and seldom do, so it's interesting to hear that backed up by someone with so much experience.
I believe he practiced and taught for many years before he made his transition, didn't he?
What is the copyright date?
I notice the purblisher looks like it might be English, and if I remember right you might be in England. I wonder if it is available in the States? Anyone know?
