"Three-fourths of our bodies is water. The human body is like a water bag. Do we the debtors gratefully thank water? How thirsty does one become en route when one rides a bicycle along a mountain ridge on a hot summer day. There are usually orchards there along a mountain ridge. just think how pleasant the taste of a cup of water being offered would be. It is worth millions of dollars. After drinking such water one might thank the one who provided the water but hardly anyone thanks water. Does anyone say "Thank you, Mr. water?' No, they don't do it."
