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 … The bat that flits at close of eve Has left the brain that won't believe. The owl that calls upon the night Speaks the unbeliever's fright … Joy and woe are woven fine, A clothing for the soul divine; Under every grief and pine Runs a joy with silken twine … Every tear from every eye Becomes a babe in Eternity… The bleat, the bark, bellow, and roar Are waves that beat on Heaven's shore … He who doubts from what he sees Will never believe, do what you please. If the Sun and Moon should doubt, They'd immediately go out … God appears, and God is Light, To those poor souls who dwell in Night; But does a Human Form display To those who dwell in realms of Day.

(William Blake)
