The poem
THERE'S no use in weeping, Though we are condemned to part: There's such a thing as keeping A remembrance in one's heart:
There's such a thing as dwelling On the thought ourselves have nurs'd, And with scorn and courage telling The world to do its worst.
We'll not let its follies grieve us, We'll just take them as they come; And then every day will leave us A merry laugh for home.
When we've left each friend and brother, When we're parted wide and far, We will think of one another, As even better than we are.
Every glorious sight above us, Every pleasant sight beneath, We'll connect with those that love us, Whom we truly love till death !
In the evening, when we're sitting By the fire perchance alone, Then shall heart with warm heart meeting, Give responsive tone for tone.
We can burst the bonds which chain us, Which cold human hands have wrought, And where none shall dare restrain us We can meet again, in thought.
So there's no use in weeping, Bear a cheerful spirit still; Never doubt that Fate is keeping Future good for present ill !

Seeing as Charlotte Bronte went through so many deaths in her life, this poem could easily be about dealing with them and her thoughts everytime someone close died. In the last stanza, she says, "So there's no use in weeping,
Bear a cheerful spirit still;
Never doubt that Fate is keeping
Future good for present ill !"
This is pretty straight foward. It basically says that there is no use in crying since fate will balance out life in the end. We know she is talking about someone dying because she says "We can meet again, in thought".
