Feeling Helpless Under British Rule: Tagore revealed in his letter that the Jallianwala Bagh massacre proved the helplessness of Indians as British subjects. The Indians are oppressed, powerless, and helpless under the British colonial rule. He wrote that the brutal killing proved the "helplessness of our position as British subjects in India." This unfairness deeply troubled Tagore, and he renounced his knighthood title.

Unjust Punishments: In his letter to Lord Chelmsford, Tagore points out that the punishments given to the people were too severe. Tagore believes that such cruel actions have "no political expediency, far less moral justification." This means that the actions taken by British rule were neither useful nor morally right.

Solidarity with His Countrymen: By renouncing his knighthood, Tagore stands beside his countrymen to protest against the brutality of the British colonial rule. In the letter, Tagore criticizes the British rulers for ignoring the suffering of the Indian people. He is upset that the British government does not care about how the Indians feel and continues to be "callous" or unfeeling.

Protest Against Injustice: Tagore feels that keeping the knighthood would be wrong when such injustices are happening. He writes,

The time has come when badges of honour make our shame glaring.

Patriotism and Moral Duty: Tagore's actions show his deep patriotism. He believes it is his duty to speak out against injustice. He writes in his letter to Lord Chelmsford,

The very least that I can do for my country is to take all consequences upon myself in giving voice to the protest of the millions of my countrymen.

In conclusion, Rabindranath Tagore renounced his knighthood because he could not accept the British government's cruel treatment of the Indian people, especially the massacre in Punjab. His letter clearly explains his reasons. His letter clearly shows his deep love for his country.
