There is a yoga meditation, that is suppose to help massage your internal organs, it involves a smile. I first heard about this, when my Mom was doing yoga on PBS. Lilias Folan was the new age instructor.
You can find articles on this, but at the time she did have it, on a VHS, later a cassette, now on cd.
When you practice "the inner smile" it helps to bring a sense of calm and well being. Yoga Journal has an article that describes it well. If you aren't into yoga, then are many other ways to enjoy an inner smile. I find
doing something for someone else, a loved one, or a stranger brings joy. A random act of kindness can leave a lingering effect.
Flowers make me smile, their scent and extraordinary, beauty brighten my day. Picking a bouquet and
giving it to a neighbor or friend is a great way to extend a smile inward and out. Gifts from the heart are my fav!
Lips leaning inward
Mind memories dancing
a curve tilted up
I hope you find a way today, to extend a smile; It will help you inside and out!
