“Continually trying to look on the bright side interferes with our finding the wisdom that lies in the fruitful darkness. Continually striving upward toward the light means we never grow downward into our own feet, never become firmly rooted on the Earth, never explore the darkness within and around us, a darkness without whose existence the light would have no meaning. To become rooted in ourselves, in the world, we have to grow down as much as we grow up. To find the fertilizer that feeds our growth, we need the rich dark loam that lies within our deepest selves.”
