Unless you change your social order you can achieve little by way of progress. You cannot mobilize the community either for defense or for the offense. You cannot build anything on the foundations of caste. You cannot build up a nation, you cannot build up morality. Anything that you will build on the foundations of caste will crack, and will never be a whole. – Babasaheb Dr. B.R Ambedkar
