New Way of practicing Old Beliefs

[Alan V]

I recognize that I've worked up a definition of spirituality here which is different from how many people use the word.

Per Wikipedia:

"There is no single, widely agreed-upon definition of spirituality. Surveys of the definition of the term, as used in scholarly research, show a broad range of definitions with limited overlap. A survey of reviews by McCarroll, each dealing with the topic of spirituality, gave twenty-seven explicit definitions among which 'there was little agreement'. This causes some difficulty in trying to study spirituality systematically; i.e., it impedes both understanding and the capacity to communicate findings in a meaningful fashion."

This is why I typically don't use the word. It's too vague, so you have to define it before you can discuss it.

So let's take (temporarily, tentatively) the definition of spirituality to be "a value system which emphasizes first and foremost efforts to be more grateful, appreciative, aware of and connected to other life in the world, and humble about one's place in the world." 

You are defining spirituality as attempting to overcome or offset one's own subjectivities. In that sense, it is about struggling to be more honest, no God or system required.
