SEA
All water is holy. The earth's water cycle is a closed system and, as such, all water is connected. All water is one. We all share the same resource. All life requires water.
The sea is deep and thick and unknowable. She is mysterious and unforgiving. She is vast and full.
To pray to water you say a blessing over water. Dip 3 fingers in the water and anoint the forehead of yourself or another. It has been done.
