Analysis of Eternal Rest

When the impatient spirit leaves behind
The clogging hours and makes no dear delay
To drop this Nessus-shirt of night and day,
To cast the flesh that bound and could not bind
The heart untamable, the tireless mind,
In equal dissolution shall the clay
That once was seer or singer flee away--
It shall be fire and blown upon the wind.
Not us befits such change in radiance dressed,
Not us, O Earth, for whom thou biddest cease
Our grey endurance of the dark and cold.
These eyes have watched with grief, and now would rest;
Rest we desire, and on thy bosom's peace
The long slow change to unremembering mould.
