Inspired by Gandhiji’s ideals of Swaraj, Truth and Ahimsa, Konwar set up a primary school at Bengmai and served as its honorary teacher.

He organised the Congress party and lead the people of Sarupathar area in Satyagraha and non-cooperation movement against the British.

Since then, Kushal Konwar pledged to remain a vegetarian and accepted the Shrimad Bhagawad Gita as his only companion.

In spite of Gandhiji’s appeal for peaceful non-cooperation and dharna, in many regions the movement erupted in violence with people burning offices and damaging government properties, disrupting road, , and telecommunication networks.

Tayebulla, Omeo Kumar Das, Debeswar Sarma, etc., were arrested from different parts of Assam and thrown into jails.

On 10 October, 1942, hidden in the thick fog of early morning, Indian independence activists removed sleepers from a railway line near Sarupathar in Golaghat district.

Humphrey, issued arrest warrants to all Indian National Congress members in the immediate area.

An ardent follower of Gandhiji and his principle of nonviolence, Kushal was ignorant about the sabotage plan and action.

When his wife, Prabhavati visited him in the Jorhat jail, he told her that he is proud that God has selected him to be the only one among the thousands of prisoners to give the supreme sacrifice for the country.

Kushal spent his remaining days in the death row cell of Jorhat jail in prayers and reading the Gita.
