A common Christmas carols says – Peace on Earth, Goodwill to man – I think it is from "I Heard the Bells on Christmas Day". The song was on the car radio. I started thinking… peace. For many it means no war or persecution. For others, it means not having to deal with anything that is drama or is negative.
I like this poster that says, and I paraphrase, peace is being calm in your heart. That feels right.
