'Prayer is a journey, sometimes a combatThere are trials, purifications, passages.It is at once the most simpleand the most profound of human activities.May these pages help someoneto discover its hidden joy.'Interior Prayer contains the Carthusians' traditional doctrine on prayer 'from its very beginnings to the simplicity of its highest forms. Far from being abstract and theoretical, we learn about the prayer process by sharing in the novices' concrete spiritual journey. Their problems and difficulties, and the many pitfalls they encounter on the way, are expressed in an ongoing dialogue with their guide who relates to each one individually.
