"People interested in Centering Prayer often ask: "Which of Father Keating's books should I read first?" This single volume contains the three basic books for the practice of Centering Prayer and its conceptual background." "Open Mind, Open Heart deals with how to practice Centering Prayer. Since its first appearance in 1986, this book has been read and used by tens of thousands of people all around in world, including many inmates of U.S. prisons. Father Keating's books have been translated into numerous languages, including Croatian, Czech, Finnish, Japanese, and Korean. A new Spanish translation of Open Mind, Open Heart appeared in 2001." "Invitation to Love treats the conceptual background of Centering Prayer rooted as it is in the Christian contemplative heritage. It is a presentation of that heritage in dialogue with contemporary science, especially developmental psychology and anthropology." "The Mystery of Christ is a series of homilies based on the liturgical year. It develops the theological principles on which Centering Prayer is based using the scriptural texts of the liturgical cycle as a primary vehicle of instruction. This instruction is embodied in the principal feasts of the year celebrating the themes of divine light, divine life, and divine love." The trilogy contained in Foundations for Centering Prayer and the Christian Contemplative Life develops the material presented in the Ten-Day Intensive Centering Prayer Workshop, in which the method of Centering Prayer is taught (Open Mind, Open Heart) along with its conceptual background (Invitation to Love). The homilies that were given during the liturgy integrate the method and its conceptual background into the mystery of Christ (hence The Mystery of Christ).
