"on ne voit bien qu'avec le coeur. L'essentiel est invisible pour les yeux."
( we only see well with the heart . the essential is invisible for the eyes .)
i know it is not really what you wanted to say . but your words created a mental image in my head that led to that association ... it reminded me of the book i so much loved as a kid (and still do as a grown up)
i hope to be able to see stuff with my eyes closed .
