When was the last time you allowed yourself to stare at something beautiful? Not something dark, violent, sad or angering, but beautiful. How did it make you feel?
I have found that it elevates my mind and increases as sense of expectation for good things. Human beings have been known to find a world view and then go about, looking for evidence that their world view is true. So why not look about for things that warm your heart and make you hope for great things? I've noticed of myself that being surrounded by people who are beautiful on the inside has changed me for the better rather quickly.
Besides this, when one views beautiful things (or actions) one gets lost in the moment, transfixed. More and more behaviorists are seeing the benefits of being completely absorbed in your work/play/moment. Better concentration, increased immune systems, relaxed muscles as well as many other benefits are the outcomes of getting "in the zone" as some call it.
I could tell you about all the sources I've read, seen and listened to.
But why not try it yourself?
What do you think?
