There is a beauty in the world that I can't point my fing

There is a beauty in the world that I can't point my finger to it, yet I feel it in my bones. the beauty of some unspoken, unexpected, unwanted, moments, things or people. Like when a person sees a book in your hand and randomly just talks about it with you and then just leaves you. While you are left with a millions of thoughts, feelings or questions. And you never know their name or story; you know in that moment through the pages of that book your souls touched.
