To me, SPIRITUAL=IMAGINARY. Some people would define spirituality as a feeling of oneness with god or oneness with the universe. I view spirituality as wishful thinking claptrap.
However, I certainly don't view my thinking as the final word on the subject, and if someday confronted by "God", I will gladly say, "oops, I was wrong and I'm sorry, but you masked your existence in vague, contradictory and confusing writings".
