Because it is Ash Wednesday tomorrow, I give you the first few lines of T.S. Eliot's poem of the same name.
Because I do not hope to turn again
Because I do not hope
Because I do not hope to turn
Desiring this man's gift and that man's scope
I no longer strive to strive towards such things
(Why should the aged eagle stretch its wings?)
Why should I mourn
The vanished power of the usual reign?
It's one of my favorites – go find it in your local library and give it a read! Or even better, listen.
