Penczak does an amazing job of keeping Wiccan bias out of this book. It's a thoughtful book about all the paths toward mysticism and what ways work for some people and what ways work for others. The exercises especially I liked, since he made sure to always give different examples and say that it's okay if that doesn't work for you. I'm surprised that at the end he equated Witchcraft with Wicca, but I guess it can't be perfect! I'm looking forward to reading some of his other books.
