You can only smile with your eyes closed by Modi

A graffiti by Mr. Modi, to which he gives a very beautiful caption 'You can only smile with your eyes closed'. Which can have many interpretations. I want you guys to give your interpretations. Mine is that you can only smile, be at peace, when you are meditative. Many new and wonderful experiences happen with eyes closed. Eyes are masculine, aggressive, ears are femanine, receptive.
