“Thy breath comes to me whispering an impossible hope.”
Longing for what seems beyond reach still carries a form of hope, even while the speaker openly recognizes distance, limitation and uncertainty.
Source note: The Gardener, poem 5, translated by Tagore from Bengali; Project Gutenberg #6686. The poem repeatedly addresses the “Great Beyond” and “Far-to-seek,” so the hope is lyrical longing rather than a factual prediction.
