“Cultivation of mind should be the ultimate aim of human existence”, these prudent words were uttered by the great dignitary of India, Dr. B.R. Ambedkar. Popularly known as Babasaheb Ambedkar and the Father of Indian Constitution, his importance in Indian polity cannot be overstated. He was an eminent jurist, social reformer and politician who fought all his life to remove discrimination, degradation and deprivation from the society. Dr. Ambedkar came from a humble middle class Dalit family and barely had money to make the ends meet. Throughout his life, he faced the stigmas of caste discrimination. Despite all this, he was determined to rise above all odds and completed his education. His works are testimony enough of the vastness and depth of his studies, wisdom and the free-feeling thought and greatness of his qualities which are eloquently refulgent in his works. Shortly after returning to India, he launched full-fledged movements for Dalit rights and found ways to reach to the people and made them understand the drawbacks of the prevailing social evils. In addition to that, he founded the Independent Labour party. His reputation as a scholar led to his appointment as free India’s first law minister and chairman of the committee responsible to draft a constitution for independent India. As drafter and ‘prime mover’ of the new Indian Constitution, Ambedkar also had a central role in guiding his committee towards the sort of socialistic, idealistic vision that he had, and that to some extent he also shared with Nehru ji. But making a constitution was not at all anybody’s cup of tea. It definitely pre-supposes a pre-knowledge of the various constitutions prevailing in the contemporary world, deep knowledge on law and, after all, a thorough understanding of Indian history and ethos, without which a step ahead would invite apprehensions of dangerous proportions in the given situations. This document thus was first and foremost, a ‘social document’ i.e. one which identified many of the basic problems besetting and needing to be addressed, for the amelioration of the masses and in this regard it is worthwhile noting down point-wise some of Dr. Ambedkar’s main, personal contributions, depending upon his own expertise and concerns:1. Guarantees of basic civil liberties to Indian citizens2. Abolition of all forms of discrimination of caste and creed, freedom of religion and abolition of ‘untouchability’ in principle at least something very personal for him, coming as he did from untouchable origins.3. Equal rights under law to Indian women, and full social and economic freedom/s to them, too.4. Various job quotas guarantees for scheduled castes and tribes and minorities in India, to ensure fair play and some modicum of ‘removal’ of social inequalities for remote and underprivileged communities.Though it was a team of seven eminent persons under his leadership, all died and deserted him for this work. Dr. Ambedkar wrote the whole text single-handedly, as a duty to parliament, in-spite of his bad health and busy personal social service.As the Constitution that the Nation got was the longest in the world, so was the process of making it prolonged and highly debated. It tooktwo years eleven months and eighteen days to make it. These were no small achievements personally, and along with their adoption, the whole of the Indian Constitution was thereafter formally passed by Parliament (Constituent Assembly) on 26th November 1949. The committee produced such a complete and commendable constitution which not onlysucceeded in giving a viable democracy to India but in upholding and maintaining unity in diversity of Indian society and culture. In this regard the comment of Baba Saheb Dr. Ambedkar in the Assembly on 25th November,1949 is remarkable; he said, “The constitution, I offered may be good or bad, it will depend on how the men in office use it”. It means, “However good a Constitution may be, if the executors fail to deliver, it may prove to be a bad one, and if the executors are good enough, however bad the constitution may be, it will definitely prove to be good.” On the 26th November, 1949 Dr. Rajendra Prasad, in his inaugural speech announced in his memorable style that the Constitution Assembly in the whole has been successful in giving us a commendable constitutionand expressed confidence that would be effective enough to fulfill the needs of India, but opined that the success of a constitution will depend much on the ability, integrity and character of the elected representatives. If they lack in the qualities, however ideal constitution may be, it will fail to deliver.Dr. Bhim Rao Ambedkar was a great son of India. As the architect of Indian Constitution, his contribution remains unmatched. His experiences as a member of the depressed class was an open book for himself which guided his future course of action to achieve the goal of his dreams.The eradication of untouchability and casteism will remain his unforgettable tribute to the making of the modern legacy in the country. His motto of struggle for the right and not against anything definitely saved India from more possible turmoil’s. His inducements and indictments will always keep the unprivileged inspiring and the atrocious deterred. The secular sentiments of the constitution are the refulgent of his liberal and all-assimilative mindset. The posthumous award of “Bharat Ratna” to him was really deserved. But, no amounts of awards or laurels can match his personality, pursuits and performances. The extent of his achievements has definitely secured for him a unique and fluoroescent place for him in the annals of history. The world will remember him as a messiah and as a man of destiny, who designed and defined the destiny of a nation and a people.
