Swami Vivekananda (12 January 1863�4 July 1902), born Narendra Nath Datta was an Indian Hindu monk. He was a key figure in the introduction of Indian philosophies of Vedanta and Yoga to the western world and was credited with raising interfaith awareness, bringingHinduism to the status of a major world religion in the late 19th century.Excerpt-We say Newton discovered gravitation. Was it sitting anywhere in a corner waiting for him? It was in his own mind; the time came and he found it out. All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in your own mind. The external world is simply the suggestion, the occasion, which sets you to study your own mind, but the object of your study is always your own mind. The falling of an apple gave the suggestion to Newton, and he studied his own mind. He rearranged all the previous links of thought in his mind and discovered a new link among them, which we call the law of gravitation. It was not in the apple nor in anything in the centre of the earth.
