Burnt Norton (excerpt), T.S. Eliot

Time present and time past
Are both perhaps present in time future,
And time future contained in time past.
If all time is eternally present
All time is unredeemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.
Footfalls echo in the memory
Down the passage which we did not take
Towards the door we never opened
Into the rose-garden. My words echo
Thus, in your mind.
But to what purpose
Disturbing the dust on a bowl of rose-leaves
I do not know.

At the still point of the turning world. Neither flesh nor fleshless;
Neither from nor towards; at the still point, there the dance is,
But neither arrest nor movement. And do not call it fixity,
Where past and future are gathered. Neither movement from nor towards,
Neither ascent nor decline. Except for the point, the still point,
There would be no dance, and there is only the dance.
I can only say, there we have been: but I cannot say where.
And I cannot say, how long, for that is to place it in time.
The inner freedom from the practical desire,
The release from action and suffering, release from the inner
And the outer compulsion, yet surrounded
By a grace of sense, a white light still and moving,
Erhebung without motion, concentration
Without elimination, both a new world
And the old made explicit, understood
In the completion of its partial ecstasy,
The resolution of its partial horror.
Yet the enchainment of past and future
Woven in the weakness of the changing body,
Protects mankind from heaven and damnation
Which flesh cannot endure.
