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.
The correct meaning of the statement The Vedas are beginningless and eternal is that the law or truth revealed by them is permanent and changeless.
-Swami Vivekananda
