Query: COMPREHENSIVE, WELL WRITTEN AND ACCESSIBLE

Manly Palmer Hall is a borderline writer on Occultism and belongs to a period when there still weren't any proper academics writing on the subject. Nowadays, I suspect that Hall's work is frowned upon in academic circles. Still, I think that THe Secret Teaching of all Ages is one of the most comprehensive, accessible and interesting books written on the Occult and there is wealth of information to be found there: Dyonisian Architects, Freemasonry (incidentally,it is debatable that Hall was a 33 degree Freemason as some sources state) rosicrucians, Tarot, Yoga etc etcA very enjoyable and profitable read.
