Milan Kundera, "The Unbearable Lightness of Being"
"We can never know what to want, because, living only one life, we can neither compare it with our previous lives nor perfect it on our lives to come."
"There is nothing heavier than compassion. Not even one's own pain weighs so heavy as the pain one feels with someone, for someone, a pain intensified by the imagination and prolonged by a hundred echoes."
