text: This was the first Collin Wilson book I read.  He has probably read a lot to write this book, but to anyone at least a little into the occult it is clear that he have no idea what he is talking about.
  If you are interested in this matter (the occult knowledge) as something you would read about but never, ever try to verify if it is true or practice anything, maybe this book is ok.
  But if you are serious about it and really want to know what true and what is fake, please stay away from this book.  He is so wrong about even simple things that could have been verified with just a few months of practical experimentation.
