Is the darkness the shadows of the rocks under the water, or the rocks over the water?
Dapples of incandescent blue shimmer and pool on the moving water, each an infinite system of particles that mirror the whole creation. Water patterns that echo the stones on the beach, the sand, and the high clouds in the huge sky, even the Universe, has the unerring pattern and structure, whether we recognize it or not.
Colours so bright, no paint could imitate them, and so transient that it could never be captured as a timeless moment. The depth of the water, the sand underneath, the sailing clouds above, all contribute to the unpredictability of what is happening all around.
Perspectives change once the body is in the massive vat of liquid, and judgments are almost always wrong. Distances seem closer than they really are, and it is easy to go quite far out without realizing it. Without the orientation of the water markers, of the headlands and the stony strand, the swimmer is lost.
