Sudden in a shaft of sunlight

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.
Sudden in a shaft of sunlight
Even while the dust moves
There rises the hidden laughter
Of children in the foliage
Quick now, here, now, always —
Ridiculous the waste sad time
Stretching before and after.
