How every ending is the start of something new. That line of thinking took me back to the days when I studied the tarot. The Tower is the card that came to mind. The card of sudden change; an unexpected ending that opens up new challenges; the tearing down of old ideas opening up new ways of thinking of life.
I also thought of the old idea of the circle of life. In my college days, my favorite professor called it the spiral of life because of how while you circle back to the same line in life's journey your path has lead you to the next plane at that same part of the circle of life. Things are the same, yet not the same.
And the circle keeps turning.
