The poem sets two states side by side: sitting still and moving. When the speaker sits, they feel empty and stuck. "I have no wind" suggests no breath, no energy, no inspiration, and the "six bottles" hint at idleness, perhaps drinking, or just clutter left on a table. The image is flat and a little lonely.
Once the speaker starts walking, things change. "All my old words again" suggests a language that belongs to the speaker and to a familiar place, which fits the title's idea of a native coming home. Walking seems to loosen speech and thought.
The last two lines are quieter and more mysterious. Saying something "its own way" sounds like language finally behaving naturally, without strain. Then "calling up a fox" lets that language seem to summon a wild animal, as if words and landscape answer each other. The mood is calm, alert, and quietly joyful, a sense of coming back to oneself.
