What Grounds You?

One of the things that brings me deep joy is walking by the ocean. There is a marked difference between walking on dry sand, which can shift this way and that, making it hard to find your footing, and walking on wet sand. Wet sand has a bit of give to it, but that place where the ocean has met the land, it is truly a magical place for me. 
I love to walk barefoot, watching my foot prints both settle and be swept away. It grounds me, not just in body, but in spirit. 
Havre you had that experience? Being grounded in your spirit. Letting peace settle over you, even when you don't understand it. Where do you experience that place where the holy meets the ordinary in your life?
