spirituality does not in itself have to be connected with religion...but then again, it is all in your perception of the definition.
I think spirituality is simply recognizing that there is something more either within you or outside of you (or both) that is bigger than your ego or perception allows you to see.
To me spirituality is recognizing that there is an interconnectedness and relationship between all things in the universe. My spiritual path is trying to uncover or understand my relationship with the rest of the world.
Aiki has been a one great way to allow me to walk on the spiritual path.
