My Heart Leaps up When I Behold - William Wordsworth

My heart leaps up when I behold     

A rainbow in the sky: 

So was it when my life began;  

So is it now I am a man;  

So be it when I shall grow old,     

Or let me die! 

The Child is father of the Man; 

And I could wish my days to be 

Bound each to each by natural piety.
