Adrienne von Speyr, a renowned mystic and spiritual writer from Switzerland, was received into the Catholic Church at the age of 38 by one of the theological giants of the 20th century, Fr. Hans Urs von Balthasar, on the Feast of All Saints, 1940. Balthasar became her spiritual director and confessor until her death in 1967, during which time Adrienne was favored with many gifts of authentic mystical prayer. Balthasar considered one of the central characteristics of Adrienne's prayer to be her transparency to the inspirations she received from God, along with a deep personal communion with the saints.Over a period of many years, Adrienne would see the saints (and other holy people) at prayer, and she would dictate what she saw to Fr. von Balthasar - while she was in a state of mystical prayer. This book presents these powerful, unique mystical insights into the prayer lives of many saints and holy people taken from Adrienne's direct visions of them in prayer. Here are the names of just a small number of the Saints whose prayer lives we get a glimpse of in this amazing book: St. John the Apostle, St. Augustine, St. Francis, St. Thomas Aquinas, St. Ignatius of Loyola, St. Teresa of Avila, St. John of the Cross, St. John Bosco, St. Edith Stein and many, many more. Fr. von Balthasar gathered these spiritual vignettes into the first volume of the "Nachlasswerke" (works intended to be published only after Adrienne's death), the Book of All Saints. In this amazing spiritual work, the reader is able to participate in the devotional and spiritual life of the Church throughout the centuries by learning how numerous saints and holy people prayed, thus reflecting on the timelessnessand beauty of the prayer of the Church.
