Of winter’s lifeless world each tree Now seems a perfect part; Yet each one holds summer’s secret Deep down within its heart.

The stanza contrasts winter’s apparent deadness with the hidden continuity of life. The trees look fully integrated into a “lifeless world,” suggesting stillness, dormancy, and even resignation; yet the speaker insists that each tree contains “summer’s secret” within. The “heart” metaphor turns botanical dormancy into an emotional and spiritual image: beneath hardship or barrenness, vitality and renewal persist. Read more broadly, the lines offer a quiet argument for hope and patience—what seems finished or frozen may be only resting, storing energy for a future season. The poem’s calm certainty makes it a consolatory meditation on resilience and cyclical time.
