Create a black and white watercolor illustration that captures the essence of the zen story titled 'the empty boat'. the scene should depict a serene, fog-covered lake with two boats approaching each other. one boat should be well-maintained, freshly painted, and clearly occupied by a figure representing the zen master. the other boat should appear empty, drifting aimlessly towards the first boat. the impending collision should be evident, but the overall atmosphere should be calm and ethereal, emphasizing the zen philosophy of reflection and non-attachment. the fog should add a layer of mystery, symbolizing the misconceptions and illusions we often hold in our minds. the water's reflection can subtly hint at the moon or other elements to represent deeper introspection and the idea of things being not as they seem.
