I got the book through interlibrary loan some months ago. Unfortunately, I wasn't able to read its contents sufficiently to get a complete picture before returning. I definitely agree with most of Nate's commentary.
It's rather of the kind of books suggesting Jesus was a Yoga adherent who visited India than presenting facts like the appearance of Epicurean vocabulary in the letters of Paul.
What I still find quite interesting is Hannah's suggestion that the Gospel of Thomas shall be a reliable and unaltered source while the other gospels are said to be compiled fiction. But this is off topic.
