There is something calming about the sound of water flowing. It doesn’t really matter if it’s just a small babbling brook or even the roar of a mighty waterfall — the sound of water moving in nature is peaceful (provided, of course, that you know that you’re safe from the water). If I sit and close my eyes and listen to a stream or the ocean surf, I can enter a peaceful realm in my mind, where my troubles just disappear for a little while. When you’re surrounded by a peaceful setting in nature, then it’s all the more pronounced. I could just sit here and be at peace for hours.
