The childhood name of Swami Vivekananda was Narendra. He was inquisitive by nature. He would ask umpteen questions. He was never at ease till he got the answers. He would not rest even after getting content with the answers. He would experiment and experience it himself and get satisfied only if he got the result likewise.
This is also how he saw the God, following instructions from his guru Ramakrishna Paramahansa.
