Analysis of To Sleep

FOND words have oft been spoken to thee, Sleep!
And thou hast had thy store of tenderest names;
The very sweetest, Fancy culls or frames,
When thankfulness of heart is strong and deep!
Dear Bosom-child we call thee, that dost steep
In rich reward all suffering; Balm that tames
All anguish; Saint that evil thoughts and aims
Takest away, and into souls dost creep,
Like to a breeze from heaven. Shall I alone,
I surely not a man ungently made,
Call thee worst Tyrant by which Flesh is crost?
Perverse, self-willed to own and to disown,
Mere slave of them who never for thee prayed,
Still last to come where thou art wanted most!
