Dame Kindness, she is so nice!
The blue and red jewels of her rings smoke
In the windows, the mirrors
Are filling with smiles.
What is so real as the cry of a child?
A rabbit's cry may be wilder
But it has no soul.
Sugar can cure everything, so Kindness says.
Sugar is a necessary fluid,
Its crystals a little poultice.
O kindness, kindness
Sweetly picking up pieces!
My Japanese silks, desperate butterflies,
May be pinned any minute, anesthetized.
And here you come, with a cup of tea
Wreathed in steam.
These could be metaphors for her poetic mind, uniquely beautiful and desperate, “anesthetized” by kindness. Alternatively, the Japanese silks and trapped ‘desperate’ butterflies may be flimsy, foreign representations of Plath’s delicate psyche. She was at a stage of her life when she was close to suicide. 
 
 The line endings in the third stanza are clever and interesting. ‘Butterflies’ and ‘anesthetized’ are closely if imperfectly rhymed, to give a neat, concise ending to the two related ideas. But Plath also subtly rhymes the first three lines as well, with the  consonant  ‘poultice’ and ‘kindness’, and ‘pieces’. There are also  sibilant  ’s' sounds throughout. These effectively unify the stanza.
