Sometimes it is necessary to point out a general misbehavior or fault that exists in somebody to teach and conclude a particular subject. Srila Bhaktivinoda Thakura gives the example of Sukadeva Gosvami in Srimad-Bhagavatam. He speaks about envious householders who are engaged in sex life, and then during the day, they are engaged in making money. Therefore sometimes it is necessary to speak about a general class of people and give them a particular instruction to make it clear that we should try to avoid this type of misbehavior. Thus, we have to be discriminating, and we have to know what the wrong type of mentality is. But we should not always dwell on it. We should look within ourselves to see our own tendencies and not always dwell on the faults of others.
