Does "After Great Pain a Formal Feeling Comes" by Emily Dickinson suggest that sorrow can make people see beauty where they did not see it before?...

I would say that Dickinson is not necessarily suggesting
that sorrow can make people see beauty where they did not see it before in her poem
"After great pain a formal feeling comes". Instead, one could justify that the power one
has to overcome sorrow lies within them.

Dickinson depicts
the great sorrow one faces through the numbing imagery of "freezing persons
recollect[ing] the snow." Here, Dickinson is showing how numb one can become when faced
with such sorrow as it over takes them. (The imagery here represents that people frozen
by sorrow can do nothing but lie still and allow more sorrow to build up upon
them.)

At the end of the poem, Dickinson admits that there
are times where one needs to feel the freezing affects of sorrow. The only way one can
overcome sorrow is to recognize that it is not allowing them to move on with their
lives--freezing them in their tracks.

The last line of the
poem, "first chill, then stupor, then letting go", shows the movement that people must
go through to find peace and beauty. Without experiencing sorrow, one cannot look
forward in order to break them free from the frozen state to which they
belong.

Therefore, it is not necessarily beauty which one
is looking for to save them from sorrow, but the strength one must find from
within.
