In the depth of winter, I finally learned that within me there lay an invincible summer.
The frost performs its secret ministry, Unhelped by any wind.
Samuel Taylor Coleridge
On a lone winter evening, when the frost Has wrought a silence.
"Shed no tear - O, shed no tear!
The flower will bloom another year.
Weep no more - O, weep no more!
Young buds sleep in the root's white core."
- John Keats
