Prabhupāda: The wise man becomes by knowledge, not by age. Even an old man, if he has no knowledge, what is...? He is not wise man. Wise means one who has attained knowledge. He may be young, he may be old. It doesn't matter. Vidyatvaṁ vayasā vinā. In Sanskrit word, that one becomes elderly without being advanced in age. That means he knows the knowledge. Therefore he is elderly. An elderly person means advanced in knowledge, not by age.
Father Tanner: Hm. But, you see, knowledge and attainment aren't the same thing. You know, I may know that it is wrong to be an alcoholic, and maybe I am not actually, physically an alcoholic, but it doesn't mean to say that interiorally I have cleansed myself of all addiction. The fact that you are not drinking for a year doesn't mean to say that you have overcome the intoxicant urge if that is in you, although you know it is wrong.
Prabhupāda: No, this argument is not very strong. Just like one foodstuff, freshly made, it is fresh. But if somebody argues that if it remains four days more, it will become bad, that is surmisation. Now it is fresh. We take it fresh. What will happen in future, that is no consideration. In future, everyone may fall and everyone may become elevated. But we have to take his present situation, what he is at present.
Father Tanner: But couldn't it be the difference between appearance and reality?
Prabhupāda: This is reality. If at the present moment he is free from all sinful activities, that is reality. In future, everyone is susceptible to fall down. If he does not carry the principles strictly that proneness is there. But that is not consideration. What he is at present, that is consideration.
Father Tanner: But what he is at present may be an accident.
Prabhupāda: Why accident? Which is actually happening, why it is accident?
Father Tanner: Well, for instance, if you take a man shipwrecked on an island alone, he is not in any sense taking part in impure love, or illicit love. But it doesn't mean to say that he is free from all desire for illicit love.
Prabhupāda: No. Nobody's free. But so long he acts nicely, he's nice.
Father Tanner: So it is the action, rather than the, no, the exterior rather than the interior.
Prabhupāda: No, interior... Well, of course, everyone has got interior tendency, but by practicing actually, exteriorally, that interior also is reformed. It is, by external behavior, the interior behavior also becomes fixed up. By practice. Therefore there is regular class so that he may be purified internally and externally. Sa bāhyābhyantara-śuciḥ. Yaḥ smaret puṇḍarīkākṣaṁ sa bāhyābhyantara-śuciḥ. If you constantly remember the Supreme Lord, so you become automatically purified, internally and externally. Because the Lord is absolute, so if we chant the Lord's holy name, the name is also Lord. He has no difference between His name and Himself.
