spirituality is the quality of being concerned with the human spirit or soul as opposed to material or physical things.
quillbot rephrased this as "Spirituality, to me, is the quality of caring for the human spirit or soul rather than material or physical objects."
you could also say that spirituality is having a need to care for the human spirit/soul rather than tangible objects.
there are many ways to rewrite the definition or make it written in your own words so have fun haha
