Ambedkar's response to the Poona Pact 
A translation of Babasaheb's Marathi speech delivered at Indian Merchant's Association Hall on 25th Sept.1932 regarding Poona Pact and published in the issue of the "Janata" on Oct. 1 1932, and excerpted from "Dr. Babasaheb Ambedkar - Writings and Speeches Vol. 18, Part I, pp. 368-369": "When I think about my difficult situation few days before and today's happy moment I consider it as a dreamlike moment. On the one hand I had to save the life of Mr. Gandhi; on the other, I had to protect the legitimate rights of millions of my fellow untouchable brothers with the full value of my life. I had never thought that this double perplexing situation will be resolved so easily and successfully. I am very happy that all the Hindu leaders showed a great understanding and took a totally thoughtful and cooperative stance in the moment of this terrible and responsible situation so that we could arrive at a satisfactory solution to come out of this very complex situation. This could be possible only due to the struggle and vehement efforts made by Mahatma Gandhi for it. I was very surprised when Mahatma Gandhi accepted and gave assent to all my demands and even congratulated me. If he had adopted the same stand in the Second Round Table Conference, this difficult situation wouldn't have arisen. I am very happy to give acceptance and assent to this successful pact. If my Upper Caste brothers wholeheartedly accept and try to implement this pact, then I and my untouchable brothers would be very happy. On this occasion I do not hesitate to give credit to Sir Tejbahadur Sapru and C. Rajgopalachari besides Mahatma Gandhi for the success of this Pact."
