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.
When we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were but we shall understand the whole thing. The same phenomena will remain but with a new meaning.
-Swami Vivekananda
