DIFFICULTIES in mental prayer are not to be thought of as blocks or problems in prayer. Those difficulties can become prayers themselves. Dom Eugene Boylan's purpose is to discuss the nature and ways of prayer from the point of view of the individual. It is not a scientific analysis nor a certified catalogue of various difficulties, but rather, it is modern spirituality at its best: a book that will encourage the reader to press on and to persevere and to struggle in prayer, no matter what.
