Bittersweet by Shauna Niequist. one of the best books.
You think you can't pray very well? You find your mind wandering when you pray? You want to have a deeper prayer life but you haven't found a discipline that works for you? Order this book and try it. You will learn a method of using your hands, your eyes, and your heart, all together at once, to focus your attention in prayer. The author teaches a method of intercessory prayer (praying for others) in detail and offers briefer suggestions for other kinds of prayer. All rely on the very simple method of drawing and coloring shapes - yes, doodling! - to focus your attention as you pray.
praying in color, an interesting and worthwhile pursuit, especially for those who struggle to pray.
a really good artistic author. good inspiration for artistic journaling.
this may not be a "product", but it's one of my favorite books.
