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
