The great leader envisioned a world where every citizen has dignity and prosperity.

Upon reaching India in 1959, the Rev. Dr. Martin Luther King Jr. remarked, “To other countries I may go as a tourist, but to India I come as a pilgrim”. He added, “Perhaps, above all, India is the land where the techniques of nonviolent social change were developed that my people have used in Montgomery, Alabama, and elsewhere throughout the American South. We have found them to be effective and sustaining — they work!”

The guiding light whose inspiration got Dr. King to India was Mohandas Karamchand Gandhi, the Mahatma, the Great Soul. On Wednesday, we observe his 150th birth anniversary. Gandhi Ji, or Bapu, continues to give courage to millions globally.

Gandhian methods of resistance ignited a spirit of hope among several African nations. Dr. King remarked: “When I was visiting in Ghana, West Africa, Prime Minister Nkrumah told me that he had read the works of Gandhi and felt that nonviolent resistance could be extended there. We recall that South Africa has had bus boycotts also.”

Nelson Mandela referred to Gandhi as “the Sacred Warrior” and wrote, “His strategy of noncooperation, his assertion that we can be dominated only if we cooperate with our dominators, and his nonviolent resistance inspired anticolonial and antiracist movements internationally in our century.”

For Mr. Mandela, Gandhi was Indian and South African. Gandhi would have approved. He had the unique ability to become a bridge between some of the greatest contradictions in human society.

In 1925, Gandhi wrote in “Young India”: “It is impossible for one to be internationalist without being a nationalist. Internationalism is possible only when nationalism becomes a fact, i.e., when peoples belonging to different countries have organized themselves and are able to act as one man.” He envisioned Indian nationalism as one that was never narrow or exclusive but one that worked for the service of humanity.

Mahatma Gandhi also epitomized trust among all sections of society. In 1917, Ahmedabad in Gujarat witnessed a huge textile strike. When the conflict between the mill workers and owners escalated to a point of no return, it was Gandhi who mediated an equitable settlement.

Gandhi formed the Majoor Mahajan Sangh, an association for workers’ rights. At first sight, it may seem just another name of an organization but it reveals how small steps created a large impact. During those days, “Mahajan” was used as a title of respect for elites. Gandhi inverted the social structure by attaching the name “Mahajan” to “Majoor,” or laborers. With that linguistic choice, Gandhi enhanced the pride of workers.

And Gandhi combined ordinary objects with mass politics. Who else could have used a charkha, a spinning wheel, and khadi, Indian homespun cloth, as symbols of economic self-reliance and empowerment for a nation?

Who else could have created a mass agitation through a pinch of salt! During colonial rule, Salt Laws, which placed a new tax on Indian salt, had become a burden. Through the Dandi March in 1930, Gandhi challenged the Salt Laws. His picking up a small lump of natural salt from the Arabian Sea shore led to the historic civil disobedience movement.

There have been many mass movements in the world, many strands of the freedom struggle even in India, but what sets apart the Gandhian struggle and those inspired by him is the wide-scale public participation. He never held administrative or elected office. He was never tempted by power.

For him, independence was not absence of external rule. He saw a deep link between political independence and personal empowerment. He envisioned a world where every citizen has dignity and prosperity. When the world spoke about rights, Gandhi emphasized duties. He wrote in “Young India”: “The true source of rights is duty. If we all discharge our duties, rights will not be far to seek.” He wrote in the journal Harijan, “Rights accrue automatically to him who duly performs his duties.”

Gandhi gave us the doctrine of trusteeship, which emphasized the socio-economic welfare of the poor. Inspired by that, we should think about a spirit of ownership. We, as inheritors of the earth, are responsible for its well-being, including that of the flora and fauna with whom we share our planet.

In Gandhi, we have the best teacher to guide us. From uniting those who believe in humanity to furthering sustainable development and ensuring economic self-reliance, Gandhi offers solutions to every problem.

We in India are doing our bit. India is among the fastest when it comes to eliminating poverty. Our sanitation efforts have drawn global attention. India is also taking the lead in harnessing renewable resources through efforts like the International Solar Alliance, which has brought together several nations to leverage solar energy for a sustainable future. We want to do even more, with the world and for the world.

As a tribute to Gandhi, I propose what I call the Einstein Challenge. We know Albert Einstein’s famous words on Gandhi: “Generations to come will scarce believe that such a one as this ever in flesh and blood walked upon this earth.”

How do we ensure the ideals of Gandhi are remembered by future generations? I invite thinkers, entrepreneurs and tech leaders to be at the forefront of spreading Gandhi’s ideas through innovation.

Let us work shoulder to shoulder to make our world prosperous and free from hate, violence and suffering. That is when we will fulfill Mahatma Gandhi’s dream, summed up in his favorite hymn, “Vaishnava Jana To,” which says that a true human is one who feels the pain of others, removes misery and is never arrogant.

The world bows to you, beloved Bapu!
