No mockery in this world ever sounds to me so hollow as that of being told to cultivate happiness. What does such advice mean? Happiness is not a potato, to be planted in mould, and tilled with manure. Happiness is a glory shining far down upon us out of Heaven. She is a divine dew which the soul, on certain of its summer mornings, feels dropping upon it from the amaranth bloom and golden fruitage of Paradise.
