In her book on rivers, Akiko Busch writes:
"In Theory of Colours, his study of wavelength theory of light and color published in 1910, the German philosopher and writer Johann Wolfgang von Goethe said of the color blue, "But as we readily follow an agreeable object that flies from us, so we love to contemplate blue, not because it advances to us, but because it draws us after it."
I wonder if that is why we feel "blue" when someone dies, even though we know that for them it is a birth and release. I wonder if we are being drawn after them, and then, we can only go so far, and they continue on into what we perceive as dark and we drop back into the air we breathe and need, for now.
