Some more words from Jacques Lusseyran, who as I said in an earlier post, was blinded in an accident at age eight. He writes about the way this allowed him to develop his capacity for paying attention which goes far beyond just the ability to see and think :

[Those who can see] commit a strange error. They believe that we know the world only through our eyes. For my part, I discovered that the universe consists of pressure, that every object and every living being reveals itself to us at first by a kind of quiet yet unmistakable pressure that indicates its intention and its form. I even experienced the following wonderful fact: A voice, the voice of a person, permits him to appear in a picture. When the voice of a man reaches me, I immediately perceive his figure, his rhythm, and most of his intentions. Even stones are capable of weighing on us from a distance. So are the outlines of distant mountains, and the sudden depression of a lake at the bottom of a valley.

This correspondence is so exact that when I walked arm in arm with a friend along the paths of the Alps, I knew the landscape and could sometimes describe it with surprising clarity. Sometimes; yes, only sometimes. I could do it when I summoned all my attention. Permit me to say without reservation that if all people were attentive, if they would undertake to be attentive every moment of their lives, they would discover the world anew. They would suddenly see that the world is entirely different from what they had believed it to be.
