Analysis of Sonnet XLI. To Tranquility

IN this tumultuous sphere, for thee unfit,
How seldom art thou found--Tranquillity!
Unless 'tis when with mild and downcast eye
By the low cradles thou delight'st to sit
Of sleeping infants--watching the soft breath,
And bidding the sweet slumberers easy lie;
Or sometimes hanging o'er the bed of death,
Where the poor languid sufferer--hopes to die.
Oh, beauteous sister of the halcyon peace!
I sure shall find thee in that heavenly scene
Where care and anguish shall their power resign;
Where hope alike, and vain regret shall cease,
And memory--lost in happiness serene,
Repeat no more--that misery has been mine!
