What Does it Mean to be "Spiritual"

The old word, "agnosticism" to me covers the wide range of people who wonder about something, anything, beyond what can be seen. It seems to cover all the kinds of things people carry in their minds to explain what may be beyond the reach of understanding. However, the term "agnosticism" has gone out of style and to some extent replaced by the word "spiritual." Even the word "spiritual" is not preferred by some who have figured out a way to navigate their own personal journey through life. There is nothing wrong with making up new ways or words to deal with the unknown or not understood. For myself, it's easier to fall back on old words. The link is about a young mother who left Mormonism and Christianity but wants something to replace it. 

Paraphrasing the link, her form of agnosticism includes a "box", I guess in could be literal or imaginary, and one puts all one's religious deceased ancestors in the box. The box is treated with reverence, "The linage in this box gave me my life. I hold it in honor and affection."

Then at family gatherings, she is enthusiastic about her relatives still in the faith. Somehow, she finds news about the church life of relatives interesting and she encourages it. I do some of this I must admit. 

She has four children and she avoids exposing them to the "lessons" of scripture but has rituals. Her children are to add an idea each year do something for others. 

Perhaps the reluctance to use a catch-all word like agnosticism among non believers is like the reluctance among religious people to stay with denominations. People in denominations have, since forever, formed breakaway denominations that are "better" than to old one. The new group often uses the term "reformed." It just happened to all the major denominations over homosexuality. 

It is understandable non believers want their own brand of "reformed" or "more correct" agnosticism. I'm not aware of a "reformed" atheism group, but that may be next.
