"It is the worker who is attached to results that grumbles about the nature of the duty which has fallen to his lot; to the unattached worker all duties are equally good, and form efficient instruments with which selfishness and sensuality may be killed, and the freedom of the soul secured."

- Swami Vivekananda, "What Is Duty" (Beginning karma yoga class, Dec 20, 1895, New York Vedanta Society), Karma Yoga, Complete Works: Vol 1
