The Valkyries - Paulo Coelho

This is the first of Paulo Coelho's books I have read and perhaps that was a mistake. I found the first half of his journey intriging and compelling but when the Valkyries appeared it all seemed to be a bit too much. It went from simple explanations eg the 'second mind' to 'hard to digest' rituals and characters. I found myself asking 'is this book factual?', perhaps if I had read his other works first I would have had more of an understanding of his beliefs and practices.
