As long as renunciation is practiced for spiritual progress, so long it is the right way. But as soon as renunciation has become a principle, it 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 a man's life they become idols; and it is not idols that we should worship; it is the ideal behind the idol.
