Gabriela Mistral's poem Meciendo contains the following stanza:
Dios Padre sus miles de mundos
mece sin ruido.
The translation on LyricsTranslate goes as follows:
God, the Father, your thousands of worlds
swing silently.
Ursula K. Le Guin's translation is a bit different:
The Father rocks his thousand worlds
silent, mild.
(Selected Poems of Gabriela Mistral, translated by Ursula K. Le Guin. University of New Mexico Press, 2003, page 56.)
What are the "thousands of worlds" supposed to refer to?
