Water
The force of water is tremendous. It can wear down solid rock over time. It can move the earth in massive chunks. It is essential to all life; without it, everything on earth dies. Floods of it can ravage the land while a tiny stream brings beauty, gentleness and life to its surroundings. The shear power and strength of water creates wonder and awe. No matter who you are, if you underestimate the force of water, it can be to your detriment. Conversely, the gentle beauty of the sunlight glinting off of a water's surface can bring calm, reflection and healing to one's soul. Watching waves crashing in along a shore can be extremely therapeutic and generate a mystical experience for the viewer.
