As far as the study goes, I am trying to not define "spiritual experience" for anyone. The idea is that each person may have their own idea of what spirituality or "spiritual experience" mean, and I don't want to influence people's ideas. My goal is to see if there are similarities or differences among different climbers.
But, to answer your question: Yes. Meditative, deeply moving, supernatural, or that which deals with the "spirit" each count in my book as spiritual. As long as it counts for you as spiritual, in whatever way that may mean, I'd love to hear what you have to say.
