Famous quotes containing the words lean and/or burn:
“Study me then, you who shall lovers be
At the next world, that is, at the next spring:
For I am every dead thing,
In whom love wrought new alchemy.
For his art did express
A quintessence even from nothingness,
From dull privations, and lean emptiness:
He ruined me, and I am re-begot
Of absence, darkness, death: things which are not.”
—John Donne (1572–1631)
“My faith shall wax, when thou art in thy waning.
The world shall find this miracle in me,
That fire can burn when all the matter’s spent:
Then what my faith hath been thyself shalt see,
And that thou wast unkind thou may’st repent.—
Thou may’st repent that thou hast scorn’d my tears,
When Winter snows upon thy sable hairs.”
—Samuel Daniel (1562–1619)
