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 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.
Wordsworth uses the term “natural piety” to imply either a devotion to nature, or the existence of a divine nature in natural forms. He wishes to always have a devotion to nature every day he exhibits it. Be and Piety could also be a slant rhyme in this poem.
