“Our birth is but a sleep and a forgetting: 
The Soul that rises with us, our life’s Star, 
Hath had elsewhere its setting, 
And cometh from afar: 
Not in entire forgetfulness, 
And not in utter nakedness, 
But trailing clouds of glory do we come 
From God, who is our home: 
Heaven lies about us in our infancy! 
Shades of the prison-house begin to close 
Upon the growing Boy, 
But he beholds the light, and whence it flows, 
He sees it in his joy; 
The Youth, who daily farther from the east 
Must travel, still is Nature’s Priest, 
And by the vision splendid 
Is on his way attended; 
At length the Man perceives it die away, 
And fade into the light of common day” (Wordsworth).

Wordsworth is saying that human live in a more pure or real world before they actually live on earth. And that as children we secretly remember memories of “heaven” and that earth damages our view as we grow up. This relates to the beginning of the poem where he says that everything he see’s in earth is pure and that Mother Nature creates everything she wants or that everything she makes is beautiful – dreamlike. Is Wordsworth saying that as children our “heaven” is our imagination? and thats why as we grow up these memories fade?
