As a sceptic and person-oriented for science, this book came as a sort of revelation, I don't believe it is 100% accurate but it made me ask some questions and not be so certain in my personal beliefs. I think the author has a very personal experience and tries to explain it. It is a hard book to read because it is so intense and full of information. I give it 5 stars for the introduction of something new and totally different from what we are used to, it made me ask some serious questions, life isn't what we believe in, it's much more. I like a quote from this book "How can we prove something that can't be proven scientifically", we can't and maybe never will but that doesn't mean it doesn't exist. The ending conclusions are interesting
