he had to have made it up. maybe the result of some crazy dream.
i heard of this book before. my roommate and i are both agnostic and this one girl (who's nice but VERY christian) got upset when we were joking when we said that hell would be a nice place to spend eternity, so she ran over to her dorm, grabbed this book, and brought it back to my dorm to show us both the horrors of hell.
i opened the book to a random page and found it to be full of incongruencies. for instance one part said that the author saw nothing but a thick black smoke obscuring his vision. in a few sentences he then went on to describe something far above his head. what happened to the smoke?
i just had to comment on this, it was such a coincidence.
