I bought this book when I was thinking of doing post-grad study in spirituality. The collection of introductory essays at the front surveys the current issues in the field from a range of perspectives and this ultimately enthused me to take the plunge and undertake the study. I am glad I bought this book as it was a constant help. As with all theological type 'dictionaries' one does not read it from end to end, but I have to admit that whilst looking up headings I was frequently way laid by the many other interesting articles! The editor's choice of approach is perhaps less traditionally theological than the (also excellent) New Dictionary of Catholic Spirituality edited by Michael Downey, but it is none the worse for that and its focus is of course more ecumenical. As with many specialist reference works this is not cheap to buy but the excellent introductory summaries and bibliographies to such a wide range of material really helped focus my reading and probably saved piles of money in the long run.
