I found this scene in the bathroom at the hospital. Sure, it was in an older part of the hospital, an adminstrative area, but it still made me pause.
To the casual observer, the water coming out of the faucet looks so clear and colorless. The water seems so pure and clean. But, over time, its true contents become evident. You start seeing the evidence...the residue...of the tiny impurities invisible to the naked eye.
Very few things are truly pure in life, even those things that are life-giving...Yin and Yang.
