If the spirit is what gives us life, then spirituality is really focused on what it means to be a living being. What makes us alive? What animates us? What makes us do what we do, think the way we think, and feel the way we feel?
Using this definition, it would seem that spiritual pursuits should be those things which make us more alive, more vital, more animated. Our spiritual life should be made up of those things which drive us, motivate us, and enrich our lives.
And all of those things which life enables us to do then become sacred in a way. Our spirit gives us capabilities as living beings, and to be spiritual is to celebrate and elevate those capabilities. In fact, it could be argued that traditions which ask us to limit what we do, to avoid fully exploring and reveling fully in what life allows us to experience, is counter to spiritual development.
