The poem, "Mirror" by Sylvia Plath talks about transcience of life with figurative language which consists of metaphors and personification. At first the mirror speaks in the poem, mirror is personified.
I am silver and exact. I have no preconceptions.
Whatever I see, I swallow immediately.
Just as it is, unmisted by love or dislike
I am not cruel, only truthful –
The eye of a little god, four-cornered.
Most of the time I meditate on the opposite wall.
The actions like "swalwing" and "meditating" gives a kind of animation to the mirror.
I see her back, and reflect it faithfully
These actions too are animated and even the lake is personified enough to communicate with the reader about the lady who comes over there to know how she look like. Such personification is found in this poem by Plath.
