Light breaks on secret lots,
On tips of thought where thoughts smell in the rain;
When logics dies,
The secret of the soil grows through the eye,
And blood jumps in the sun;
Above the waste allotments the dawn halts.
Dylan Thomas, Light breaks where no sun shines

Day dawdled at my elbow. It was night
Within. I saw my hands, their soft dark backs
Keeping me from the noise outside. The candle
Seemed snuffed into a deep and silent pool:
It drew no shadow round my constant image
For in a dazzling dark my spirit stirred.
