I really don't see any conflict between the way I look at the world and an interest in spirituality, although that certainly depends on your definition. Christians definitely don't think I'm spiritual, because to them spirituality is a personal relationship with a dead guy and his non existent father, who is also him (looks like somebody got a hold of a time machine

). A lot of atheists probably wouldn't consider me spiritual either, because to them spirituality means belief in supernatural agents.
I don't believe in belief. Or rather, I don't believe in belief as method of determining facts about the cosmos that have a good chance of corresponding to an external reality assuming there is such a thing. That's actually one of the things that got me interested in Eastern concepts of spirituality in the first place, because it's very concerned with the nature of subjective experience and undoing conditioning in an effort to see the world as it is.
