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
The less passion there is, the better we work. The calmer we are, the better for us and the more the amount of work we can do. When we let loose our feelings, we waste so much energy, shatter our nerves, disturb our minds, and accomplish very little work.
-Swami Vivekananda
