"The word "spiritual" normally means something that's distinct from the fleshly or the material. It's not of the world. But that version of spirituality is bankrupt today. It had its use when the program of science divested matter from the spiritual qualities - - the qualities of a self, or of a being. When science divested the world of those qualities and made it into just a thing, rather than a self, it gave us license to treat it as just a thing, and not as something sacred, conscious, alive, intelligent. So this is tied into the whole trajectory of our civilization."
