Thorsten doesn't talk about supernatural powers or abilities. He explains that everything what he does is based on earthly skills and practice like body language, human psychology and other known sciences. The good news is that everybody can master such abilities, but the bad news is that you will need determination, time and hard work to do that. It's like any other science or skill, you need to work on that and be focused.
One of the message that you can find in the book is that all people who pretend to be some future readers, spiritual healers or similar - are fake. After reading this book you will understand that quite clearly.
One of the beautiful things about this book is that there are a lot of exercises that you can start practicing right away and start understanding the principles of the "magic". To sum up all above, this book gave me a start and a new passion. It's really very interesting sphere, which is very useful as well. For me it's just a start, and I believe that you will be astonished as well.
Are you still going to believe in playing cards or coffee grounds?
