I view religion in terms of organized religions - rigid systems of thought and ritual. I can't name any one religion I subscribe to or practice.

It is possible to be spiritual and explore spiritual understandings of God and life without subscribing to a particular religion.

One primary difference is that religion asks you to accept the religion as the authority, an authority outside of yourself. If what people find within them differs, the religion says it is wrong.

Spirituality is the exploration of one's inner truth. There is no outside authority.

My spirituality is more what you might perceive of as advanced science. Science and spirituality eventually merge. Science is approaching conclusions that mystics arrived at long ago (regarding the nature of reality, matter, time, space, etc).
