Founders of the Constitution gave us a map and moral framework, the task of "walking that path remains our responsibility", President Droupadi Murmu said in her address to the nation on the eve of 74th Republic Day on Wednesday.

She said the founding document is inspired by the humanistic philosophy of the oldest living civilisation in the world as well as new ideas that emerged in more recent history.

"The nation will always remain grateful to Dr B R Ambedkar, who headed the Drafting Committee of the Constitution, and thus had a critical part in giving it the final shape. On this day, we should also remember the role of jurist B N Rau, who had prepared the initial draft, and other experts and officers who helped in making of the Constitution," she said.

The President said the country is proud of the fact that the members of that assembly represented all regions and communities of India and that they included 15 women too.

"Their vision, as enshrined in the Constitution, has been continuously guiding our Republic. During this period, India has been transformed from a largely poor and illiterate nation into a confident nation marching on the world stage," she said.

The President said the transformation would not have been possible but for the "collective wisdom of the Constitution makers" guiding our path.

"While Babasaheb Ambedkar and others gave us a map and a moral framework, the task of walking that path remains our responsibility. We have largely remained true to their expectations, and yet we realise that much remains to be done to realise Gandhiji’s ideal of ‘Sarvodaya’, the upliftment of all. Yet, the progress we have made on all fronts is encouraging," she said.

The President said such a vast and diverse multitude of people coming together as one nation remains unprecedented.

"We did so with a belief that we are, after all, one; that we are all Indians. We have succeeded as a democratic republic because so many creeds and so many languages have not divided us, they have only united us. That is the essence of India," she said.

Murmu said that essence was at the heart of the Constitution, which has withstood the test of time.

"The Constitution that started governing the life of the Republic was the outcome of the Freedom Struggle. The national movement, led by Mahatma Gandhi, was as much about winning Independence as about rediscovering our own ideals," she said.

Those decades of struggle and sacrifice "helped us win freedom" not only from colonial rule but also from the imposed values and narrow world-views, she said.

"Revolutionaries and reformers joined hands with visionaries and idealists to help us learn about our age-old values of peace, brotherhood and equality.

"Those who shaped the modern Indian mind also welcomed progressive ideas from abroad, following the Vedic advice...'Let noble thoughts come to us from all directions'. A long and profound thought process culminated in our Constitution," she said.
