My heart leaps up when I behold!!! Help! Can u tell me anything about it?

Answer 1

This is a poem 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:
And I could wish my days to be
Bound each to each by natural piety.

Answer 2

It is poem in which the author says he wants to retain the sense of wonder he had, as a child, all through his life.
