Quite right.

To me spirituality is something like a feeling, comprised of part wonder, part awe, part feeling small and part feeling all. DMT experiences have been deeply spiritual as they have this element of something 'higher' that has no english definition besides the term 'spiritual'. It's simply something 'more' that can only be experienced and never truly explained. Perhaps neuroscientists would disagree, but I have to give credit to any scientist who digs spirituality and does not dismiss it. And a lot of them have taken psychs... go figure.
