Book excerpt: This updated edition of The Oxford Handbook of Psychology and Spirituality codifies the leading empirical evidence in the support and application of postmaterial psychological science. Lisa J. Miller has gathered together a group of ground-breaking scholars to showcase their work of many decades that has come further to fruition in the past ten years with the collective momentum of a Spiritual Renaissance in Psychological Science. With new and updated chapters from leading scholars in psychology, medicine, physics, and biology, the Handbook is an interdisciplinary reference for a rapidly emerging approach to contemporary science. Highlighting fresh ideas and supporting science, this overarching work provides both a foundation and a roadmap for what is truly a new ideological age.
