This quote by Dr. B.R. Ambedkar highlights the underlying difference between eminent and great people. An eminent person is one who is well known and commands respect in the society owing to his/her proficiency and expertise in his/her field. Eminence can be achieved by excelling in certain fields, gaining knowledge, or developing breakthrough technology. For example, a scientist who has done a breakthrough research or invention can be referred to as an eminent personality.
However, becoming great is an arduous task. For this, one needs to champion the cause of humanity and be ready to serve the society beyond personal benefits or recognition. A great person need not be a master in his profession, but is virtuous. He/she is the one who devotes himself/herself for the betterment and well-being of others.
The significance and relevance of the quote can be further understood by following examples:

• Dedicated to betterment of society: Great personalities are needed who can devote themselves for the creation of a better society and future. Social reformers like Rajaram Mohan Roy, Ishwar Chand Vidyasagar worked relentlessly for the upliftment of women and making an equitable society.
• Spearheading the cause of downtrodden and marginalized: Individuals such as Jyotiba Phule, Savitri Bai Phule offered the best possible support and help for the cause of women education with limited resources. They were empathetic to the cause and dedicated themselves, which makes them great.
• For inclusive development: Dr. B.R. Ambedkar himself devoted his whole life against social evils such as untouchability, caste divide etc. He was a staunch supporter of equality of all and an advocate of Dalit rights.
• To lead at the time of crises: Societies or nations need a leader at the time of crises. Great personalities are also leaders needed by the society who serve as a harbinger of new ideas and instil hope in masses for change and betterment.
  • For example, Mahatma Gandhi took the leadership role during the Indian freedom struggle so that the country could free itself from foreign occupation and imperialism.

Thus, a great man is ready to serve the society for the greater good of the mankind. He is not concerned about the parochial view of self-benefit. When thoughts of I, me, myself transform to we, us and ours then a person becomesgreat. The civil services also require such people who are willing and able to sacrifice their personal interests for the larger public interests and help steer the society and the country towards a better future.
