Selfless service and love are twin divine qualities. Only the one who loves can serve.
Serve your beloved God-Man and you are serving your own self in every other self.
The service he exacts is for your own spiritual benefit; but this service must be spontaneous, willing, wholehearted, unconditional and not expecting any reward. His service is an ordeal which tries body, mind and spirit, or else wherein would the perfection of serving lie if it were to be easy and at one's convenience. The body suffers, mind is tormented, but the spirit of the selfless server of the Master experiences the bliss of satisfaction.
Only the one who has can renounce. A king's giving up his everything and becoming a beggar is his true renunciation; and so only the one who, without any question and regardless of consequences, serves the God-Man, really serves; otherwise it would be just like paid labor.
