The eight illustrations are an integral part of this book inasmuch as Paul Claudel's meditations revolve about the pictures reproduced here. There is a Rembrandt and a Titian, but the other six are by modern French artists. The book itself is a series of unusual monographs all dealing with the life of meditation and prayer. While the presuppositions are those of a believing Catholic, in all but one of the chapters the appeal to cultivate the life of the Spirit is one which would strike a responsive shord in the hearts of wistful Protestants as well as Catholics. The method of presentation is such as would interest those conversant with the esoteric, and the mystical. Among the appendices added as so many afterthoughts is a reproduction of an essay by Dr. Alexis Carrel entitled ""Prayer is Power"".
