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.
May I be born again and again, and suffer thousands of miseries so that I may worship the only God that exists, the only God I believe in, the sum total of all souls--and, above all, my God the wicked, my God the miserable, my God the poor of all races, of all species, is the special object of my worship.
-Swami Vivekananda
