A Jewish Wedding

Today I went to a Jewish wedding, the first I've ever attended.  The service was beautiful,  in the woods, overlooking a creek.  I liked the traditions the Rabbi told us about, I assume because most of the attendees were not Jewish.  Anyway, the tradition of breaking the glass is one I enjoyed the most.  According to the Rabbi, in ancient times there were thought to be many demons around, and the sound of the breaking glass would scare the demons away.  The Rabbi said we still have demons that need to be scared away, the demons of jealousy, disrespect, anger and indifference.  I appreciated the analogy.  These and many other things can be demons in a marriage.
