Belief and Money

I recall an interview with a master of marketing in the 1960s who said his best product was a simple prayer on an A4 sheet of paper that he sold, at the time, by mail, for one dollar. He sold hundreds of thousands of them...money just rolled in and the roneo/photocopier thing of the time was always churning them out. It was probably a really nice prayer and I'd kind of like to have read it, in retrospect. I guess I would have printed it on some nice looking aged-type paper, but that wasn't necessary then.
It was the remarkable Teilhard de Chardin who noted that one day the God who became Man will come face to face with the Man who became God and they will notice remarkable similarities in each other to the point that they will realise that they are indeed the same being.
