Meditation Without Myth: What I Wish They'd Taught Me in Church About Prayer, Meditation, and the Quest for Peace by Daniel A. Helminiak
This book is written for Christians who were trained in a particular form of prayer wrapped up in high intellectual concepts, so never learned to meditate. Helminiak, a theologian, psychologist, and former Catholic priest gives us techniques and guidelines for meditation practice, a psychological explanation of these techniques, and a down-to-earth perspective on the metaphysical musings that surround these matters.
