These beautiful lines come from Book II of “The Prelude”:
I began
To love the sun, a Boy I lov’d the sun,
Not as I since have lov’d him, as a pledge
And surety of our earthly life, a light
Which while we view we feel we are alive;
But, for this cause, that I had seen him lay
His beauty on the morning hills, had seen
The western mountain touch his setting orb,
In many a thoughtless hour, when, from excess
Of happiness, my blood appear’d to flow
With its own pleasure, and I breath’d with joy.
