Many already value highly the published work of Evelyn Underhill, the noted Anglo-Catholic student and teacher of mysticism. This present volume gives her admirers the searching and inspiring material she used on week-end retreats, in which she likens the prayer life to the Holy Communion in which the worshipper reaches toward God as manifest in the Body and Blood of his Son. She writes of Thanksgiving, turning Pride into Humility; Sacrifice, transmuting Anger into Tranquility; Communion, setting aside envy for Charity; Commemoration, overcoming Avarice by Generosity; and Mystery, letting detachment reign over greed. Miss Underhill writes with beauty and grace, and her words become a clear channel through which the presence of God is made more real to seeking man. For devotional reading, this book will be hard to equal. The second part of the book, Miscellaneous Essays, has been published before. They have one unifying theme, the life of prayer, and so are most appropriately reprinted here.
