smile in your liver

Over break, I read the book Eat, Pray, Love by Elizabeth Gilbert.
When the narrator travels to Indonesia to study with a medicine man,
he tells her to "smile in your liver" during meditation to get rid of bad energy.

I love this little phrase and I love the idea of smiling outside and inside. This year I want people to see me smiling so much that they think even my organs must have a big smile.
