Analysis of Love's Blindness

Now do I know that Love is blind, for I
Can see no beauty on this beauteous earth,
No life, no light, no hopefulness, no mirth,
Pleasure nor purpose, when thou art not nigh.
Thy absence exiles sunshine from the sky,
Seres Spring's maturity, checks Summer's birth,
Leaves linnet's pipe as sad as plover's cry,
And makes me in abundance find but dearth.
But when thy feet flutter the dark, and thou
With orient eyes dawnest on my distress,
Suddenly sings a bird on every bough,
The heavens expand, the earth grows less and less,
The ground is buoyant as the ether now,
And all looks lovely in thy loveliness.
