Grasp those thoughts.

For the field floated free and untethered,
As if in space,
And were they to reach the edge, there would be never time
To stop them before they fell.
Hence I watched and waited and listened;
And tried so hard to be there;
Before they went tumbling away into the precipice beyond.
For once they fell, there would be no recovering them,
They were gone.
Gone but not forgotten..
