I downloaded the book too, and I don't believe most of it, but when I tried the exercise where you try to feel the tip of a pencil scratching circles on your thumb knuckle, I definitely felt exactly what he said I would feel. I'm not going to discount his techniques, even if I think his explanations may be off.

I really need to read more of the book. It's just so looooong though, and hard to find the actually useful information. Thanks for posting the technique.
