A distillation of over seventy years as a monastic and more than three decades of writing on centering prayer, Reflections on the Unknowable is Fr. Thomas Keating’s latest volume on how we might develop our intimacy with God and our experience of the Christian contemplative tradition. The first part of the book consists of a long interview with Fr. Thomas, in which he examines concepts of the divine-including the astonishments, playfulness, and transformation available to the individual willing to open the door to God. The second section consists of thirty-one brief homilies, which range over topics as diverse as the Trinity and the message of Epiphany, spiritual evolution and cultivating interior silence, and the treasure of spiritual poverty and the beauty of chaos.
