Now I feel as if I should succeed in doing something in mathematics, although I cannot see why it is so very important. . . The knowledge doesn't make life any sweeter or happier, does it?

I cannot remember how I felt when the light went out of my eyes. I suppose I felt it was always night and perhaps I wondered why the day did not come.

As selfishness and complaint pervert the mind, so love with its joy clears and sharpens the vision.

What I am looking for is not out there, it is in me.

Walking with a friend in the dark is better than walking alone in the light.

I, who have never heard a sound, tell you there is no silence, and I, who have never seen a ray of light, tell you there is no darkness.

Death is no more than passing from one room into another.
