The detail of the pattern is movement,
As in the figure of the ten stairs.
Desire itself is movement
Not in itself desirable;
Love is itself unmoving,
Only the cause and end of movement,
Timeless, and undesiring
Except in the aspect of time
Caught in the form of limitation
Between un-being and being.
-TS Eliot, Four Quartets, Burnt Norton VAdvertisements
