I usually judge non-duality books on whether they take me to the place that they are talking about, that is, silent awareness. This may have happened to you. As you are reading the words of a non-duality book, you are suddenly transported to a place of peace and tranquility. Adyashanti's books have this effect on me. This book, Eternity Now, did not take me to that place often, but it did answer in detail most of the questions relating to non-duality. It also gave me some fresh ideas on how to address problems in a non-dual way. I think anyone interested in this subject would enjoy the book.
