Pasad al interior de la cueva,
pasad con muchas flores y cantos,
haced súplicas a todos los vientos,
en el interior de la cueva.
Allí van entrando los venerados vientos.
Ante el rostro de los vientos,
aquí sobre la tierra vamos pasando,
nos ponemos de rodillas,
llevamos una, dos antorchas,
con uno, dos manojos de flores,
Venimos todos nosotros a hacer súplicas:
Que Tláloc nuestro dios
dé la lluvia al monte,
y a los hijitos de la gente,
¡Oh todos vosotros estimados señores!
¡Oh todos vosotros, venerados vientos! (s. XX)
