What I am, I must not show What I am thou could (not know) Something between heaven and hell Something that neither stood nor fell Something that through thy wit or will May work thee good, may work thee ill Neither substance quite, nor shadow Haunting lonely moor and meadow Dancing by the haunted spring Riding on the whirlwinds wing Far less happy, for we have Help nor hope beyond the grave Man awakes to joy or sorrow Ours the sleep that knows no morrow This is all that I can show This is all that you may know A year there is a lifetime And a second but a day And an older would will meet you Each morn' you come away The thunder's noise is our delight And lightning makes us day by night And in the air we dance on high To the loud music of the sky
