Denise LevertovYes, he is here in this open field, in sunlight, among the few young trees set out to modify the bare facts-- he's here, but only because we are here. When we go, he goes with us to be your hands that never do violence, your eyes that wonder, your lives that daily praise life by living it, by laughter. He is never alone here, never cold in the field of graves.
