In rendering service, one should have no thought of one’s self. One should only consider how well one can render the service as an offering to the Divine. One should note the difference between Karma (action) and Karma Yoga (action as spiritual discipline). Ordinary activity is motivated by self interest or the desire to achieve some objective. In Karma Yoga, the action is desireless. Ordinary Karma is the cause of birth, death and rebirth, whereas Karma Yoga leads to freedom from birth. You should regard all service as a form of Karma Yoga – rendering service without any expectation of reward, and without even the feeling that one is ‘serving’ others. Any service done to anyone is actually service to the Divine.
