What kind of modified GD?
do you read Austin Osman Spare?
You should read 777, it's just a table of correspondences comparing various religions/sciences with eachother, over the sephera. SO krshna or buddha or christ would all be the BEAUTIFUL sephera. It does the same for the pathways etc.

His books on yoga were also pretty good.
Well if you're a hermetic have you studied Hermes trismigestus? I think i remember sharing alink with you on the subject, the corpus hermeticum? what did you think?
