Power of Concentration
After a good vacation, its time to study and score good marks and remarks. We know that concentration is essential to get the best result in any activity. Presenting below is a short story on one of the greatest sons of India and his amazing power of concentration.
When Swami Vivekananda was traveling in the United States of America, he was staying with a friend of his in a particular town. He came across a gentleman who was in-charge of the local library. They were having discussions on the power of the mind and so on. While Vivekananda very lucidly brought out that the vast potential of the human mind is scarcely tapped by the modern man due to his poor will and the powerful forces of the pulls of tinsels of the world on him, which totally distracts him, the friend was not convinced and wanted a proof for the statement of Vivekananda. He threw a challenge to Vivekananda to go through the complete volumes of encyclopedia in his library containing information on all bodies of worldy knowledge and answer his questions from the same and thus prove the vast potential of His mind.
Vivekananda accepted the challenge and told him that the gentleman can ask any question from any part of the encyclopedia, the next day. That whole night, Swami Vivekananda went through the complete volumes on encyclopedia and because of his enormous power of concentration could memorize every bit of information contained in it. The next day, the friend asked Swami Vivekananda questions from the various volumes of encyclopedia and lo! Vivekananda answered them squarely to the utter surprise of his American friend. What a wonderful illustration of the power of concentration
