To see a World in a Grain of Sand (William Blake)

                               To see a World in a Grain of Sand

                       And a Heaven in a Wild Flower,

                       Hold Infinity in the palm of your hand

                       Eternity in an hour.

--William Blake,        

Auguries of Innocence
