"...a blink of an eye in itself is nothing. But the eye that blinks, that is something ..." - Chaim Potok

“We live less than the time it takes to blink an eye, if we measure our lives against eternity. So it may be asked what value is there to a human life. There is so much pain in the world. What does it mean to have to suffer so much if our lives are nothing more than the blink of an eye?

I learned a long time ago, Reuven, that a blink of an eye in itself is nothing. But the eye that blinks, that is something. A span of life is nothing. But the man who lives that span, he is something. He can fill that tiny span with meaning, so its quality is immeasurable though its quantity may be insignificant. Do you understand what I am saying? A man must fill his life with meaning, meaning is not automatically given to life.”
