Spring arrives in the speaker’s garden, but he doesn’t feel part of it. Everything around him blooms and renews, yet he says “I alone unchanged,” as if the season has skipped him. While the world moves into light and growth, he still lives inside his own house of autumn—a place of fading, loss, or inward retreat. The mood is quiet and isolated rather than bitter: he watches the change from a distance, aware he cannot join it.
The final image, “One leaf alone saves a tree,” is deliberately strange. It can sound like a fragile comfort—something small still keeping life going—or like a lonely burden, a single thing holding on when everything else has fallen. Either way, it captures the speaker’s state: he is that one leaf, enduring but not exactly blooming, waiting inside an autumn that only he inhabits.
