'you are no longer a child, reuven..it is almost possible to see the way your mind is growing. and your heart, too..so listen to what i am going to tell you. human beings do not live forever, reuven. 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 man who lives the span, he is something. he can fill that tiny span with meaning, so that its quality is immeasureable 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. it is hard to work to fill one's life with meaning. that i do not think you understand yet. a life filled with meaning is worthy of rest. i want to be worthy of rest when i am no longer here. do you understand what i am saying?'
