“Thank you for the sun / The one that shines on everyone / Who feels love.”

Reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 514.
Context: I cannot speak
In happy tones; the tear drops on my cheek
Show I am sad;
But I can speak
Of grace to suffer with submission meek,
Until made glad.
I cannot feel
That all is well, when dark'ning clouds conceal
The shining sun;
But then I know
God lives and loves; and say, since it is so,
"Thy will be done."

Context: p>If this is a dream, then perhaps our dreaming
Can touch life's height to a finer fire:
Who knows but the heavens and all their seeming
Were made by the heart's desire?One thing shines clear in the heart's sweet reason,
One lightning over the chasm runs —
That to turn from love is the world's one treason
That darkens all the suns.</p
