Indicate and explain the poetic devices in "The Soul selects her own Society"?

This poem uses imagery
(creating a picture in words) relating to two discrete areas: the narrator's life
indoors shown in the first line, and then the seemingly glorious and elevated events of
the outside world.

The opening line also uses
sibilance (repetition of the "s" sound) which gives the
poem a whispering, hushed tone to the poem. This is also used later in the
poem.

The repetition
(repeating a word) of "unmoved" illustrates the firmness with which the
female soul chooses her associations and sticks with
them.

The metaphor (describing
one thing as another) of "closing the valves of her attention" is an unusual one: taking
us right into the heart where such allegiances (or rejections) of others' are
made.

The final simile
(comparing one thing to another using like or as) of "Like stone" shows
the determination of the soul in establishing her relationships, and the stubbornness
with which she retains her position.
