Urgent through all the body, while each part
Obeys, and all are one—
While in her dungeons labors the lone heart
To make her will be done.
She reins the forces in their wild career
That bear her, as they go,
Over the dark abyss; and knows how sheer
Reaches the gulf below.
How dubious her life and slenderly
Hangs, by a scarlet thread,
