A wizard of words and wisdom for our times, visionary evolutionary thinker O'Murchu has produced another classic in contemporary pneumatology. Every era of human history;every indigenous culture and all world religions, have to varying degrees, directly or indirectly, formally or implicitly, attempted to understand 'Spirit Power' and to ritualise and express it in some way. In this thoroughly researched and expansive exploration of the meaning, role and place of 'The Great Spirit' in human culture and consciousness - and more importantly at the heart of the ever-expanding, open-ended creation - Diarmuid masterfully unpeels the rich layers of meaning and beauty emanating from the divine life force we commonly refer to as 'Spirit'. For too long this cosmic 'breath of life' has lain semi-dormant in theological abstraction or creedal formulations. In a world where science, religion and spirituality are informing each other like never before, this book is a thoughtful and cutting-edge 'must read' for those who, in the words of Diarmuid, care enough about the earth which sustains our growth and flourishing, and our greater cosmic home to which we integrally belong, that we pay continuous 'contemplative attention' to its unfolding mystery forever calling (luring) us forth into ever new and deeper being and becoming. Rave on Diarmuid: yes, the Spirit is indeed 'back with a vengeance!'
