I get if from a lifetime of personal experience...as a free thinker who does not belong to any group, cult, religion, or political party...but is willing to take a look at all the possibilities. I question every human custom. I question every creed. I find some good in most, if not all of them...I find that none of them has all the answers. The members of almost any group (religious or otherwise) tend to be a bit chauvinistic about other groups in the same field of interest. I question that also. I have a natural tendency to resist being pressured to conform to other people's expectations.

Of course there are different interpretations of words like "spiritual" or "spirit". I was just giving you my interpretation of it, that's all.
