Patio, heaven’s watercourse.
The patio is the slope
down which the sky flows into the house.
Serenely
eternity waits at the crossway of the stars.

In a few compressed images, the speaker turns an ordinary architectural feature of the Hispanic house—the interior patio—into a metaphysical instrument. Calling it “heaven’s watercourse” suggests the patio as a channel through which the vastness of the sky is gathered and made intimate, “flow[ing] into the house.” The domestic space becomes a threshold where the infinite is not abstract but sensuously present as light, air, and open space. The closing lines shift from architecture to cosmology: at a “crossway of the stars,” eternity is imagined as calm, patient, and already there. The poem thus links the everyday and the eternal, a characteristic Borges move: the infinite is encountered not by escape from the world but by a change in perception within it.
