Theland, I think you are thinking of spiritual in close and exclusive association with "The Spirit", i.e. an entity such as a deity, angel, etc., perhaps even "The Devil" - a personification of sorts. When non-religious people refer to something spiritual they are very often, perhaps mostly, referring to personal spirits (principally their own), i.e. a sense of existing/being. Your datum is different from theirs and actually of a different category altogether. In other's minds they can feel spiritual with or without the overlap into the religious (although the two have very large parallels), whereas you give the impression of not visualising stepping out of the religious. One way of expressing the difference would be to say that the two forms of spiritual experience are two different moods. Not everyone has a matching mood with their fellow men/women, perhaps sometimes but certainly not all the time. Can we not live with such variation, even quite happily, maybe even welcome it ?
