I've read "Initiation into Hermetics". It's a practical book meant to help initiate the neophyte, but I found the exercises not so easy in practice. I bought the book several years ago and have yet to move past the exercises in chapter 3. I suppose I'm not disciplined enough to complete the entire work.
Bardon's works are far less complicated than Crowly's and much more practical as far as I can tell. I've read some of Crowly's works years ago and they had my head spinning. At least Bardon takes the reader by the hand and guides them step by step.
I'm actually selling my copy of "Initiation into Hermetics" as I don't foresee me moving past chapter three. If anyone is interested, I have the first edition of the second English translation published by Merkur publishing in 1999. The book is in near fine condition with a dust jacket in very good condition. The value of the book is $95.00 + dollars. There's one copy of this edition posted on Amazon for $219.00, however.
PM me if interested
