Over the decades many have looked at the Mona Lisa painting, curious and mesmerized by her smile. I too have sometimes wondered why exactly she was smiling. What kind of smile is that?  It's not even a full smile? What's so special about it?

Then one day, while at my brother's house, I saw a poster of Albert Einstein. On the poster was the quote, "I want to know God's thoughts...the rest are details." And it came to me: "Oh, that's why Mona Lisa was smiling in that famous portrait. She knew God's thoughts and Einstein didn't."

Mona Lisa's was a smile of knowing. And Albert Einstein's was one of extreme frustration, for not knowing—God's thoughts.
