Imagine a still body of water, perhaps a lake or a wide part of a river. The water's surface is smooth and reflects the sky and the trees along the bank like a mirror. You can feel the imagined smoothness of the water. Above, you might imagine large, fluffy clouds in a bright sky. These clouds are reflected in the water below, creating a symmetrical image. Along the edge of the water, trees grow densely. You might imagine the varied textures of tree bark and leaves. The scene evokes a sense of peace and tranquillity, with the reflections creating a double image of the natural world.
