First published in 1986 and in print - and immensely popular - ever since, Open Mind, Open Heart, by the Trappist Monk Thomas Keating, remains one of the best introductions to a specifically Christian form of meditation. Father Keating gives the reader an overview of what contemplative prayer both is and isn't; he discusses the history of contemplative prayer in the Christian tradition and then explores step by step the process of Centering Prayer, briefly exploring its origins in the ancient church and then demonstrating its use as and "a sign of one's intention and " to surrender to God. Each chapter concludes with questions and answers that provide useful information in an informal context. Here in particular we get a sense of Keating's clarity - and his sense of humor. For example, in response to a question about the sudden experience of happiness in prayer, Keating responds, and "You should not take prayer too seriously. There is something playful about God. You only have to look at a penguin ... to realize that He likes to play little jokes on creatures. and " - Doug Thorpe
