Swami Vivekananda revealed to the world the true foundations of India's unity as a nation. He taught how a nation with such a vast diversity can be bound together by a feeling of humanity and brother-hood. Vivekananda emphasized the points of drawbacks of western culture and the contribution of India to overcome those. Netaji Subhash Chandra Bose once said: “Swamiji harmonized the East and the West, religion and science, past and present. And that is why he is great. Our countrymen have gained unprecedented self-respect, self-reliance and self-assertion from his teachings.” Vivekananda was successful in constructing a virtual bridge between the culture of East and the West. He interpreted the Hindu scriptures, philosophy and the way of life to the Western people. He made them realize that in spite of poverty and backwardness, India had a great contribution to make to world culture. He played a key role in ending India's cultural isolation from the rest of the world.
