Thomas à Kempis

The Imitation of Christ -- This book is said to have been published in more editions than any other, apart from the Bible, with 6000 appearing by the turn of this century. This little devotional book is simply written but immensely moving. Highly recommended.

St. Augustine
The Confessions of St. Augustine -- The most popular work of the man who more than any other shaped western civilization. The first 10 chapters constitute a spiritual autobiography and some spiritual and philosophical reflections; the last three chapters are a reflection on the creation story of Genesis 1.
