Imagine a lake, undisturbed.. still. Now throw a rock or even a pebble into it. You can envision the lake now having waves that span out of the area impacted to an extended area. The motion can make it pretty difficult to see what’s going on beneath the surface of the water. And should the movement come from the ground of the water, it can make it murky or muddy it, leaving it all too unclear.
Just like life and our view of the world around us..
