I wasn't even going to post anything today, but alas: I just noticed Beppie had to go and tease me by picking a quintessential Blake piece this month for her group, so there you go.
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.
- from Auguries of Innocence, William Blake, the Pickering Manuscript
(I made this some time back as a visual affirmation for myself: a copy or two of it are always hanging around somewhere.)
