In A Grief Observed, I was intrigued by Lewis' theme of reality never repeating itself. He says "Reality never repeats. The exact same thing is never taken away and given back. How well the spiritualists bait their hook! 'Things on this side are not so different after all.' For that is what we should all like. The happy past restored." He uses this theme again at the end of the book talking about "happy reunions" with our families in heaven. Lewis stresses that we should not make these reunions an End, but to keep God in focus as the true End. I had never really thought of heaven in this way and this passage made for interesting reading.
