Nouwen writes beautifully and his enthusiam for four of the most spiritually significant icons, such as the Rublev Trinity, certainly drew me in and captivated me. Indeed, this was a book that helped me a great deal in my spirtual life. The format of having four pull-out pictures of the icons, two at each end of the book corresponding to each of the four icons, were helpful because one could, if one wished, meditate on the pictures while reading the text. I found this was an excellent introduction to icons and one that I have returned to over the years for some marvellous quotations in the text, speaking as they do about the graciousness of God towards us. There is a ring-binder style of layout to this book which makes it easier to use for meditation.
