Analysis of Sonnet XLIII: Love and Hope

Bless love and hope. Full many a withered year
Whirled past us, eddying to its chill doomsday;
And clasped together where the blown leaves lay
We long have knelt and wept full many a tear.
Yet lo! one hour at last, the Spring's compeer,
Flutes softly to us from some green byeway:
Those years, those tears are dead, but only they:—
Bless love and hope, true soul; for we are here.
Cling heart to heart; nor of this hour demand
Whether in very truth, when we are dead,
Our hearts shall wake to know Love's golden head
Sole sunshine of the imperishable land;
Or but discern, through night's unfeatured scope,
Scorn-fired at length the illusive eyes of Hope.
