Letters are the reflections of one's mind. We can imagine the magnetic effect the letters of a dynamic personality and saint like Swami Vivekananda had upon the lives of those to whom they were addressed. Even a single passage of many of his letters is sufficient to bring about a great revolution and complete transformation in one's life. This volume contains all the more important letters of Swamiji
Look here -- we shall die! Bear this in mind always, and then the spirit within will wake up. Then meanness will vanish from you, practicality in work will come, you will get new vigor in mind and body, and those who come in contact with you will also feel that they have really got something uplifting from you.
-Swami Vivekananda
