effect of concentration

 Effect of Concentration: Once Swami Vivekananda came to Meerut, he was very fond of reading. That is why he used to get books from the library for reading by his disciple Akhandanand. After reading the book in only one day and returning it on the second day, the Grantpal got angry. He told Akhandanand that changing books everyday gives me a lot of trouble. You read these books that only the pages turn? Akhandanand told this to Swami Vivekanand ji, then he himself went to the library and said to the Grantmaster – I had ordered all these books, I have read all the books. You can ask me any question from these books. Grantpal had doubts that reading books requires time to understand, so he asked many questions to Swami Vivekananda to solve his doubts. Vivekananda ji answered every question correctly but this question book. Which page it is on, he also told immediately. Then the librarian was surprised to see Vivekananda ji's brilliant memory power and asked the secret of such memory. Swami Vivekananda said- 'It is necessary to study for concentration and for concentration it is necessary to have meditation, control of the senses'. We must practice meditation and tratak daily to move ahead in any field. ,
