SWAMI VIVEKANAND ' CONCENTRATION '

Swami Vivekananda was a voracious reader. While he stayed in Chicago, he used to go to the library and borrow large volumes of books and return them to the librarian in a days time. The frustrated librarian then asked Swami Vivekananda why he borrowed books when he doesn't want to read them, she was all the more annoyed when he said he finished reading all of those books. She said she would take a test and selected a random page from a book and asked him to tell what was written there; without even a glance at the book he repeated the lines exactly as they were written. She asked him several more questions and he answered all of them without a flaw.
