In the hours I've spent at Mom's bedside recently I've found myself staring at a TV screen playing a continuous loop of nature shots. There is some New Agey music that goes with it, what we used to call Muzak, only with an airier, lighter touch. But the sound is usually turned off, so I'm looking at photographs without the benefit of soundtrack.
One thing I've noticed is the similarity of the shots. Though the landscapes may be of mountains, seascapes or red-rock deserts, the foreground is usually green. There's a reason for that, I believe, something to do with our earliest origins, the safety of enclosure giving way to an open view. Splendor in doses. Domesticated wilderness.
All I know is that it is mesmerizing. I look at Mom, I look at the screen, I think of all that can be held in a head and a heart.
