Swami Vivekananda stressed on the positive attitudes of life- love, harmony, service and the like. Some of these concepts find echo in an emerging trend of psychological studies called Positive Psychology. In fact, most of these traits are considered as marks of spiritual wisdom.
As soon as you know the voice and understand what it is, the whole scene changes. The same world which was the ghastly battlefield of maya is now changed into something good and beautiful.
-Swami Vivekananda
