What is the theme of the poem "The Whorehouse in a Calcutta Street," written by Jayanta Mahapatra?

The most significant
theme of this poem, I
think, has to do with its depiction of sex workers as

individuals with identities that exist outside of the work that they do.
There is
a temptation for those who visit brothels to think of the women who
work there as existing only
for their pleasure, as though these women simply
wait, naked and willing, for them to arrive so
that they can come to life.
The speaker seems to mimic, even mock, these thoughts in the first
few
lines:

Walk right in. It is yours. />Where the
house smiles wryly into the lighted street.
Think
of the women
you wished to
know and haven't.

However, the speaker points out the
"secret
moonlight of the women" and the fact that their conversation with clients is

"false chatter" because they are really thinking of their children, their homes,
and
their own lives rather than the sexual pleasure they will provide for the
men who pay them. The
women may feign pleasure, but they are really concerned
with other, more mundane, things. These
men "miss them in the house's dark
spaces" and fail to see these women as individuals,
as people with dignity
and hope. This is perhaps symbolized by "the far edge of the
rainbow" that
they feel "faint[ly]" in the centers of their
beings.
