Exuberance is beauty. - William Blake

If the fool would persist in his folly he would become wise.

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 hell through all its regions.

This cabinet is formed of gold
And pearl and crystal shining bright,
And within it opens into a world
And a little lovely moony night.
