Analysis of The Mind's Liberty

The mind, with its own eyes and ears,
May for these others have no care;
No matter where this body is,
The mind is free to go elsewhere.
My mind can be a sailor, when
This body's still confined to land;
And turn these mortals into trees,
That walk in Fleet Street or the Strand.

So, when I'm passing Charing Cross,
Where porters work both night and day,
I ofttimes hear sweet Malpas Brook,
That flows thrice fifty miles away.
And when I'm passing near St Paul's
I see beyond the dome and crowd,
Twm Barlum, that green pap in Gwent,
With its dark nipple in a cloud.
