The sorrow of true love is a great sorrow

The sorrow of true love is a great sorrow
And true love parting blackens a bright morrow:
Yet almost they equal joys, since their despair
Is but hope blinded by its tears, and clear
Above the storm the heavens wait to be seen.
But greater sorrow from less love has been
That can mistake lack of despair for hope
And knows not tempest and the perfect scope
Of summer, but a frozen drizzle perpetual
Of drops that from remorse and pity fall
And cannot ever shine in the sun or thaw,
Removed eternally from the sun's law.
