I have been reading The Varieties of Spiritual of Spiritual Experience, 21st Century Research and Perspectives by Yaden and Newberg and found it very thorough in terms of the varieties of experience and attempts at elucidating them I have also had numerous spiritual experiences of my own and had my life changed accordingly. In my reading, I am reminded that “No process of analysis, no piling up of descriptive accounts, no reversion to antecedent causes, brings us any nearer to what we mean by beauty, goodness or love.” (Rufus Jones). I also recall that Margaret Mead once wrote that “As I understand contemporary trends of physical science, there is increasing recognition of vast unknown areas which science may explore and assist in ordering, but to which it may never provide anything like complete answers.”
