The Hindi title "विध्वंस" (transliterated as "Vidhwans") means "catastrophe" or "destruction". I am not too familiar with Urdu, but Google Translate says that "Tahreek-e Khair" means something like "good step", as in, a "step in the right direction", which is reasonably close in meaning to the title "A Positive Change" given in the Penguin Books collection.
The reason the short story has titles with drastically different meanings in Urdu and Hindi is that the Urdu version is not merely a translation of the Hindi version. Instead, it takes a completely different turn in the climax, in a way that justifies the different titles.
It is the Hindi version that has been translated into English on The Fresh Reads website linked in your post. At the end of the story, not only does <PERSON> die from throwing herself into the fire, the winds spread the flames all over the village and burn down the zamindar's mansion. Catastrophe has fallen upon the villagers with <PERSON>'s death, and especially upon the zamindar who gave her so much grief.
In the Urdu version, the consequences of <PERSON> jumping into the fire are dramatically altered. Here, the zamindar instinctively jumps in to pull <PERSON> out, at great risk to himself. 829
He manages to save her life, and he even nurses her back to health in his mansion. When <PERSON> asks him why he risked his life for an old woman such as herself, he answers:
[...] I didn't care what I was doing and why. It was as though I had lost my senses. Everything happened on its own. God wanted to save me from disgrace. What else?
Taken from the Urdu translation by <PERSON>, published in Premchand: the complete short stories, vol. 2, Penguin Books, 2017.
In this version, the zamindar seems to have had a genuine change of heart through <PERSON>'s impulsive decision to jump into the fire; hence, the title "A Positive Change".
So, in this case the difference in the titles is not due to any subtle differences between the two languages, but in the changes made to the story itself. 417
