JMG, I've always been interested in the approach and subject matter of your Sacred Geometry books, but have never got around to buying any of them. I currently try to do a standard LBRP/MP Exercise routine with divination (Tarot), meditation and a daily planetary invocation every day. I have been through your Occult Philosophy Workbook. For practical reasons, that's about as far as I am going to be able to get in Magic.
So is there any advantage in your Sacred Geometry books for me? (I see from the description that the SOP is involved, which I obviously don't do.) Or are there other books, by you or others, that you would recommend?
Grateful as always for your advice.
