OPIS
This very readable brief guide examines a wide range of spiritual writing that can be read for enjoyment or inspiration, including some books that come from beyond any religious tradition. While written from within the Christian tradition, and offering introductions to the writings of medieval mystics, Quakers and modern evangelists, both Protestant and Catholic, it also looks at classics of secular spirituality and writings from different religious traditions. Each book is explained to convey a brief idea of what each one has to offer the interested reader, while a 'Speed Read' for each book delivers a quick sense of what each writer is like to read and a highly compressed summary of the main points of the book in question.
This is an excellent reference to dip into, but within sections such as Early Christian Classics, Secular Texts, Lives of Inspiration and Alternative Approaches, the books are arranged chronologically, revealing some interesting juxtapositions and connections between them.
