O soft embalmer of the still midnight,
Shutting, with careful fingers and benign,
Our gloom-pleas'd eyes, embower'd from the light,
Enshaded in forgetfulness divine:
O soothest Sleep! if so it please thee, close,
In midst of this thine hymn, my willing eyes,,
Or wait the amen, ere thy poppy throws
Around my head its lulling charities.
Then save me, or the passed day will rise
Upon my pillow, breeding many woes;
Save me from curious conscience, that still lords
Its strength for darkness, burrowing like a mole;
After the caesura the sestet introduces a new and more sinister mood, with the first of four imperatives.  ‘Save me’ is repeated for emphasis.  Note that the indentations are reversed
