A man far away from the place where a band of music is being played does not hear its sound, while another man standing nearby feels it but little if he is deeply absorbed in his own thought, he does not find himself with music but feels himself dwelling in his own pious thought. How does he acquire this state of mind? The reply, as already said above, is that he finds himself absorbed in something of the most important nature. Then naturally the unimportant things will have no effect on him. This is the condition of vairagya, or renunciation.
