In 1942, during the Quit India Movement both she and her husband were arrested and her magazine was forced to cease. On her release in 1946, she was elected to the Constituent Assembly of India. During the partition violence, she met Gandhi in Noakhali. Even before Gandhiji reached there, she opened a relief center and rescued 400 women after touring on foot 90 miles in just six days. After the Partition of India, she ran homes in Calcutta for destitute and abandoned women and tried to help refugees from East Bengal. In 1947 she founded the Jatiya Mahila Sanghati, a women's organisation in West Bengal.
