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.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies; but the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
-Swami Vivekananda
