This clear and cogent approach to prayer remains as fresh today as it was almost seventy years ago at its original publication. Published in 1943, Difficulties in Mental Prayer soon became an international bestseller with editions published in many European languages and even in Chinese. Boylan does not present a scientific classification of the types and methods of prayer, but rather a guidebook to enable anyone to navigate the personal challenges that come with a pursuit of growth in prayer, making this an ideal book for parish retreats, adult confirmation candidates, and faith-sharing groups.
