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.
By doing well the duty which is nearest to us, the duty which is in our hands now, we make ourselves stronger; and improving our strength in this manner step by step, we may reach a state in which it shall be our privilege to do the most coveted and honored duties in life and in society.
-Swami Vivekananda
