I heard that human feel relax by listening water sounds or seeing the flow "instinctively".
Certainly, many people like to see painting of the river and the sea.
A water mill used to work for conducting water into a rice-field. We can find this water mill has a lot of themes; Japanese mind, water-flowing, circle-transmigration, colors harmony and so on.
This painting, one of the most my favorite paintings took the most time and efforts to draw. I was sometimes about to be crazy in the middle of making.
Anyway, I hope this would be peace of mind for you.
