How about "more focused"?<quoted text>
Not sure you meant it this way, but this type of statement has an air of arrogance about it with the implication that someone with an atheistic viewpoint has a less deep sense of experience of life. In a different post, you also referred to your approach as more holistic, again with the implication that ours is less holistic. May I suggest you replace the word "deeper" in your statement with "different" (unless you really meant it that way).
".....Just like you can read the paper while eating breakfast, OR eat breakfast and focus on the tastes, smells, colors, and textures of what you are eating. The latter is a deeper experience. Thats all spirituality really is, IMO.
