[1] In 1985, her mentally ill eldest son, Dharmeswar, suffered from a bout of typhoid, leading Rabha and her husband to take him to a village quack.

After this incident, Rabha realised that the superstitions that led to the diagnosis of her son were baseless and stopped visiting quacks, who she believed were frauds.

[11] Despite facing ridicule and attacks from those who defend the belief in witches, and being subjected to accusations of witchcraft herself, Rabha frequently spoke out against witch-branding and hunting at meetings, organised awareness camps and taught school lessons denouncing the practice.

[1][13] In 2015, the activist's campaigning prompted the Assamese government to pass The Assam Witch Hunting (Prohibition Prevention and Protection) Act, which many consider to be India's toughest anti-witch-hunting law.

In 2005, she was nominated for a Nobel Peace Prize by the North East Network (a women's rights organisation operating in Assam), and in 2015, was awarded an honorary Doctorate from Gauhati University.
