I was refering to the pilgrim that lived in russia, i think, and he had a withered arm. He went traveling around, looking for someone with information about the part of the bible which says to pray at all times. He eventually finds someone that tells him that you must say a prayer to yourself constantly and eventually, it becomes part of your heart beat hence you are praying at all times. I was asking about whether the book about the pilgrim exists at all. If so, is it a true story?
