It's an old Chinese saying about Budai. The original: 大肚能容,容天下难容之事;
笑口常开,笑世间可笑之人。There are many Japanese sayings about him too. Many haiku as well. I posted one of my favorites here.

btw, thank you for making the call for more to join our discord. I need to check in and see what you guys have been up to. I'm on the road right now. Hopefully my busy time will be at an end soon and I can devote more time to that.
