For example, a Kṛṣṇa conscious boy, even if he is not very well educated by the university standard, can immediately give up all illicit sex life, gambling, meat-eating and intoxication, whereas those who are not in Kṛṣṇa consciousness, although very highly educated, are often drunkards, meat-eaters, sexmongers and gamblers. These are practical proofs of how a Kṛṣṇa conscious person becomes highly developed in good qualities, whereas a person who is not in Kṛṣṇa consciousness cannot do so. We experience that even a young boy in Kṛṣṇa consciousness is unattached to cinemas, nightclubs, naked dance shows, restaurants, liquor shops, etc. He becomes completely freed. He saves his valuable time from being extravagantly spent in the way of smoking, drinking, attending the theater and dancing.
One who is not in Kṛṣṇa consciousness usually cannot sit silently even for half an hour. The yoga system teaches that if you become silent you will realize that you are God. This system may be all right for materialistic persons, but how long will they be able to keep themselves silent? Artificially, they may sit down for so-called meditation, but immediately after their yogic performance they will engage themselves again in such activities as illicit sex life, gambling, meat-eating and many other nonsensical things. But a Kṛṣṇa conscious person gradually elevates himself without endeavoring for this so-called silent meditation. Simply because he is engaged in Kṛṣṇa consciousness he automatically gives up all this nonsense and develops a high character. One develops the highest character by becoming a pure devotee of Kṛṣṇa. The conclusion is that no one can truly have any good qualities if he is lacking Kṛṣṇa consciousness.
