The speaker watches someone from a distance, or perhaps only imagines him, and everything is based on a feeling: "I get the feeling." Nothing is stated as fact. The man seems to be "very high," then slowly descending, floating into a forest like a parachutist. But the place he lands is a study. Pine trees pierce his "glass-like palace," so the room feels both fragile and open to nature. He bends over a manuscript, and his mind bends over a pencil, as if body and thought are working together.
The title, "Re-Entry," suggests a return from somewhere far away, and the poem reads like a writer coming back down from inspiration into the slow work of putting words on paper. The mood is quiet, dreamy, and a little strange. The ending adds a small mystery: the speaker hears the parachute but never sees it fall. The descent is felt, not witnessed, which leaves the man's state of mind just out of reach.
