When I was a little kid in the ‘60s, I had this dream:
I was sitting in the living room of the family house, and I asked my sister, “Did you miss your pooie-wooie?” She’s TOWERING over me, and she raises her hand like she’s going to smack me.
Move on up some twenty years; I was at a wedding, and a girl there moaned, “Oh, pooie-wooie!” How many times a day do you here “pooie-wooie”?
There are spiritual traditions that say there is no boundary between the “physical” world and the “spirit” world; they are one and the same; to a certain extent, I believe it.
