Ghalib[0], whose every poem is like a heartbreaking Koan, although it's very hard to find good English translations:
Let awareness spread wide its net of comprehension,
In my world of words, meaning is a bird of dreams.
A thousand wishes thus, that each demands a life,
I've done the best I could, but couldn't do too much.
