“Voici mon secret. Il est très simple: on ne voit bien qu’avec le cœur. L’essentiel est invisible pour les yeux.” [ENGLISH TRANSLATION]: “And now here is my secret, a very simple secret; it is only with the heart that one can see rightly, what is essential is invisible to the eye.” - Le Petit Prince (The Little Prince) by Antoine de Saint-Exupéry
