Well that is some spectacular prose, I am truly transported to a place where spirituality and science meet at a single point of grand mystery and realization that I have felt a few times in real life, alone in nature at surprising places and odd hours, but Saint-Exupéry has taken this all one further level up the rung.
To a level that my father actually lived, as an airplane pilot in Baja California back when the peninsula didn't have a paved road, an isolated, remote place as yet mostly untouched by man.
One minor caveat, however:
a sheet spread beneath the stars can receive only star-dust
While I understand such a thoughtful writer was going for a feeling, surely with his talent he could have found a way to include windstorms, all the dust and sands they can sweep horizontally across the lands and over hills. The Rio De Oro region is in northern Morocco, surely it often gets blasted by powerful Saharan winds.
A sheet spread beneath the Moroccan sky most often receives desert-dust.
