Quite slow We sat so comfortably together Under the cool roof of alders, We gazed so quietly together Down into the murmuring brook. The moon was already out, The stars after her, And we gazed so quietly together In the silver mirror there. I sought to see no moon, Nor the star's shine; I looked only at her image, At her eyes alone. And I saw her reflection nod and gaze Up from the blissful brook, The flowerlets on the bank, the blue ones, They nodded and gazed right back. And into the brook seemed sunken The entire heavens; And seemed to want to pull me under Into its depths as well. And over the clouds and stars, There murmured the brook And called with singing and ringing: Fellow, follow me! Then my eyes filled with tears, And made the mirror ripple: She spoke: "The rain comes, Farewell, I am going home."
