As long as renunciation is practiced for spiritual progress, so long it is the right way. As soon as renunciation has become a principle, renunciation is abused. Man, in fact, must be the master of life. He must use renunciation, not go under in renunciation. So it is with all virtues. When virtues control man's life, they become idols. It is not idols that man must worship, it is the ideal he must worship in the idol.
