My Heart Leaps Up When I Behold

"My Heart Leaps Up When I Behold" by 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;
     I could wish my days to be
Bound each to each by natural piety.
