We could never learn to be brave and patient, if there were only joy in the world.
When indeed shall we learn that we are all related one to the other, that we are all members of one body?
There is joy in self-forgetfulness. So I try to make the light in others' eyes my sun, the music in others' ears my symphony, the smile on others' lips my happiness.
What a blind person needs is not a teacher but another self.
To be blind is bad, but worse is to have eyes and not see.
Good friends walk in when the old ones walk out.
