"In a spiritual sense that by which a person gives birth is the formative striving of the will and that is within a person’s power. What are you afraid of then? After all, you are not supposed to give birth to another human being; you are supposed to give birth only to yourself. And yet I am fully aware that there is an earnestness about this that shakes the entire soul; to become conscious in one’s eternal validity is a moment that is more significant than everything else in the world."
