Robinson Jeffers - Joy

Though joy is better than sorrow joy is not great;
Peace is great, strength is great.
Not for joy the stars burn, not for joy the vulture
Spreads her gray sails on the air
Over the mountain; not for joy the worn mountain
Stands, while years like water
Trench his long sides. 'I am neither mountain nor bird
Nor star; and I seek joy.'
The weakness of your breed: yet at length quietness
Will cover those wistful eyes.

Robinson Jeffers
