I've met many spiritual people who would never call themselves that. They simply are themselves, deeply.
I think of 'spirituality' as a simple ladder. You don't yell out "Hey, I'm a 'ladder-stander'." the whole time you're up there. And you generelly don't announce or even notice that it is cool that you are climbing up. You just have a different place to operate from and it is fairly mundane. When you're done for the day you put your feet on the ground where you first started and prepare for your next project. You just get a little more adept at the transition with practice. No bells and whistles....just a little more proficient than when you started.
