Dark clouds become heaven's flowers when kissed by light.

The line uses a characteristic Tagorean image—nature transfigured by light—to suggest that suffering or adversity (“dark clouds”) can be transformed into beauty and meaning when touched by hope, love, or spiritual insight (“kissed by light”). The metaphor implies that what appears ominous may contain the potential for renewal, much as clouds can turn radiant at sunrise or sunset. Read more broadly, it aligns with Tagore’s recurring themes of reconciliation between sorrow and joy, and of an immanent divinity that turns the ordinary world luminous. The aphoristic form makes it function like a devotional or philosophical maxim rather than a narrative statement.
