So what is known in the scholarship of religion and spirituality at this point of the 21st century? Definitions of spirituality show a growing understanding of the breadth and content of spirituality, and yet, there remains no firm definition. In one sense, it might be good that spirituality has not been tightly defined. Swinton and Pattison (2010, p231) note, “multiple definitions may be indicative of the necessity and the flexibility of the term to meet particular needs that would otherwise go unmet.” The publication of the paper written by Agli et al. in this edition of the journal, is timely and provides an excellent systematic review of the recent literature.
