Students need both faith in God and Diksha (determination). There is the example of a great American scientist, Thomas Alva Edison. He was born in a poor family on February 11, 1847, in the state of Ohio. Although he made no progress in his studies, he became a great inventor, thanks to his supreme self-confidence and his perseverance and determination in the pursuits of his experiments. His early experiments had untoward results, which provoked his parents to punish him and ultimately to send him out of the home. For a time he earned a living by selling sweets in trains.

(Thomas Alva Edison - "Genius is one percent nspiration, ninety-nine percent perspiration.")

Once, a guard slapped him for causing explosion in the closet of a train. His hearing was affected thereby. A benefactor came into his life after he had saved a child from being run over by a train. He got a job in a telegraph company and was free to carry on his experiments. From such beginnings, Edison became the greatest inventor of our times because of his tremendous perseverance and tireless experiments. The world owes to him the electric bulb, the gramophone, the telephone and many other inventions. If without any regular schooling, Edison could achieve all this; it was because of his confidence in himself, his firm determination and tireless energy. In addition to their academic studies, these are the qualities a student should acquire. They should associate with right-minded persons, whose company will improve their mind and character.

Edison the scientist concentrated so much on the solution of the problems that worried him that he left untouched for days together the food and drink that was pushed in through the doors of his laboratory. You must have the same concentration and shraddha, while engaged insadhana. (SSS Vol.5, p. 144)
