First, let me admit something: I’m not crazy about books that anthologize excerpts of writings from other sources. I find such “taken out of context” selections to be jarring to read. But that’s just my bias, so I’m recommending What the Mystics Know even though it’s that kind of book: sort of a “best of Richard Rohr,” at least in terms of his sizable corpus of writings published by Crossroad. Broadly divided into seven categories including enlightenment, imperfection, suffering, paradox, contemplation, truth and transformation, this book gathers together much of Father Richard’s easily accessible wisdom — not only on mysticism, but indeed on life in general. If you’re not familiar with Rohr, this would be a great starting point; if you already know his work, What the Mystics Know could work beautifully as a daily devotional.
