May flit into the air you seem to rend
With acclamation, leaving me to wake
In the dark tower; or dreaming that I wake
From this that waking is; or this and that
Both waking or both dreaming; such a doubt
Confounds and clouds our mortal life about.
And, whether wake or dreaming, this I know,
How dream-wise human glories come and go;
Whose momentary tenure not to break,
Walking as one who knows he soon may wake
