To see a World in a Grain of Sand And a Heaven in a Wild Flower, Hold Infinity in the palm of your hand, And Eternity in an hour.

A Robin Redbreast in a Cage Puts all Heaven in a Rage. A dove house filled with doves and pigeons Shudders Heaven with the terror of prisoners.

A soul in the body, singing to the Void, While the Earth trembles with the sound. Let a man live, let a man die, And with the seed of his body grow sound.

• William Blake
