“I tell thee Love is Nature's second sun,
Causing a spring of virtues where he shines.”

"Bedouin Song" (1853), in The Poetical Works of Bayard Taylor (1907), p. 69.

Context: I love thee, I love but thee,
With a love that shall not die
Till the sun grows cold,
And the stars are old,
And the leaves of the Judgment Book unfold!
Context: From the Desert I come to thee
On a stallion shod with fire;
And the winds are left behind
In the speed of my desire.
Under thy window I stand,
And the midnight hears my cry:
I love thee, I love but thee,
With a love that shall not die
Till the sun grows cold,
And the stars are old,
And the leaves of the Judgment Book unfold!

" Light Breaks Where No Sun Shines http://www.internal.org/view_poem.phtml?poemID=265", st. 1 (1934), st. 1
Context: Light breaks where no sun shines;
Where no sea runs, the waters of the heart
Push in their tides;
And, broken ghosts with glow-worms in their heads,
The things of light
File through the flesh where no flesh decks the bones.
