--- T.S. Eliot, from East Coker, second of the Four Quartets
The last stanza:
Old men ought to be explorers
Here and there does not matter
We must be still and still moving
Into another intensity
For a further union, a deeper communion
Through the dark cold and empty desolation,
The wave cry, the wind cry, the vast waters
Of the petrel and the porpoise. In my end is my beginning.
