My wife took this picture a few years ago when she was traveling around the world. This picture is where two different bodies of water meet - but not really. It is the Amazon River on the left and the Rio Negro on the right. The thing is though, as you can see, these two bodies of water don't "mix." Because of differences in density and temperature, the two bodies of water stay separated even though they are in the same place. Every time I look at this picture it reminds me of how we are supposed to be "in the world" but not "of the world."
