When most I wink, then do mine eyes best see,
For all the day they view things unrespected;
But when I sleep, in dreams they look on thee,
And darkly bright are bright in dark directed.
Then thou, whose shadow shadows doth make bright,
How would thy shadow’s form form happy show
To the clear day with thy much clearer light,
When to unseeing eyes thy fair imperfect shade shines so?



William Shakespeare (Sonnet 43)
