Prabhupāda: So Yudhiṣṭhira was commissioned to speak this lie that, "You go and say that, 'Your son is dead.' " And he says that, "I never spoke lie. I cannot do that." Now here the order is coming from Kṛṣṇa; therefore he should have executed the order immediately. Although speaking lie for common man is sin, but because it is in relationship with Kṛṣṇa, it is not sin. So that telling lie should not be taken risk of at one's own discretion. It must be ordered by Kṛṣṇa or by His representative. Telling lie is always sinful. That's all right. But if Kṛṣṇa says: "Tell lie," it is not sinful. That is the secret. You can violate the laws only on the direct order of Kṛṣṇa or His representative. That's all. That is common sense.
Just like a political person is engaged to kill somebody under superior order. And if he can kill, he is rewarded, he is given high post. But the same man, if he kills by his own discretion, he'll be hanged. So serving greater purpose, supreme purpose, absolute purpose, there is no question of such piety or sinful. But in the ordinary field, there must be "This is pious, this is sinful." So that discretion should not be taken by oneself, but it should be consulted.
Jaya-gopāla: If one can engage one who is demonic in service by telling a lie . . .
Prabhupāda: General principle is that if you can engage anyone in Kṛṣṇa consciousness, that is good. That is good. That is also said in the Bhakti-rasāmṛta . . . yena tena prakāreṇa manaḥ kṛṣṇe niveśayet (Bhakti-rasāmṛta-sindhu 1.2.4). If your aim is to engage him in Kṛṣṇa consciousness, if you do something which is not very straight, that is allowed. (laughter) Because you are doing very good to him. Suppose a man is drunkard. So suppose if you say, "Oh, all right. I'll give you a very nice bottle of whiskey at cheap price. Give me fifteen dollars."
And if you take fifteen dollars and engage it (in) Kṛṣṇa consciousness, that cheating is allowed. (laughter) Because that fifteen dollars he'll take and drink. So you have by some way taken away that fifteen dollars and engaged in Kṛṣṇa consciousness. So that you have done good to him.
So therefore it requires little intelligence and discretion. (laughter) But that does not mean you shall cheat fifteen dollars from everywhere. But there is no cheating, because anyone who is not Kṛṣṇa conscious, he is a drunkard. He is drunkard, he is illusioned under material spell. You see? You see? The greatest drunkard, everyone who is not Kṛṣṇa conscious.
