Why is destiny so unfair?

Lord, which did sin, this man—or his parents that he was born blind?

The true metal, first mixed with clay, seeks the acid of suffering, and mixing and fusing with that acid is parted from the earth and shows itself in its true nature. 

When you get rid of all idea of being punished, condemned—or even injured by your inherited tendencies or by the evil example of others, you will have some clouds removed from your vision, and will have confidence in the absolute fairness of your destiny.
