Water is a compound that has made the birth of life possible. Looking from space, Earth shines out as a blue planet as most of it is covered by water. Likewise, more than half of the human body is made out of water. Leonardo da Vinci considered water as a kind of transmitter, or a vehicle of nature: vetturale di nature.

Water flows unseen in the canals of our bodies. The heart functions as a pump that maintains the organs. It keeps life in motion. Water runs through the piping of a fountain, finally splashing into the air. In a building, water travels from place to place through maundering pipelines. It flows through the roots in the ground and through subterranean pipelines. Sometimes water feels like a state of being, which fills both, the body and mind entirely. In dreams, water holds great power.
